Hourleey 3/4 Inch Brass Garden Hose Adapter Review
As an Amazon Associate we earn from qualifying purchases.
This Hourleey 3/4 Inch Brass Garden Hose Adapter review covers a two-pack of female to female couplers made from solid brass. The Hourleey Garden Hose Adapter has 3/4 inch GHT female threads at both ends, so it joins two male ends, and the package includes four spare washers. This review uses only what the Amazon listing states, plus two non-retail sources on hose-end connections and backflow. It does not report leak tests, pressure tests, or wear checks. The listing describes solid brass construction, standard 3/4 inch GHT fit, and a note that the coupler is meant for garden hose use.
Quick answer
- The listing describes two solid brass couplers with 3/4 inch female GHT threads at both ends and four spare washers.
- Check that the two ends you plan to join are both 3/4 inch male GHT before you buy.
- The coupler joins two hose ends. It does not turn a hose into a pipe connection, and the listing gives no pipe-thread option.
- The sources discuss hose connections and backflow in general. They do not rate or test this coupler.
How we chose the sources for this review
The listing details come from the product page checked on 2026-10-27. The two sources were picked because they are non-retail references on hose connections and backflow. Neither one covers this coupler, so they only give context for why hose-end connections deserve a careful check.
What the listing says
The Amazon listing for the Hourleey adapter gives the following specifications. These come from the listing checked on 2026-10-27, and they describe the seller’s product, not an independent measurement.
- Brand: Hourleey. Size: 2 Pack Female to Female. Color: Gold.
- Material: Brass.
- Connector type: Coupling. Thread size: 0.75 inch. Thread type: GHT.
- Item dimensions: 3 x 4 x 5 inches.
- Item weight: 1.6 ounces.
The About this item section says the package includes two 3/4 inch double female garden hose connectors and four spare hose washers. It describes the coupler as female to female with 3/4 inch threads on both ends, and it says both ends connect to a garden hose with a female end. It describes the material as solid brass and says the coupler is heavy duty and built for strength. It also says the coupler fits all US standard 3/4 inch garden hoses and is easy to install. The listing claims there is no water leak, which is a seller statement.
The listing also includes a note about customer service, saying the seller responds within 24 hours. That is a seller statement about support. This review does not check it.
Fit: what a female to female coupler joins
A female to female coupler is a short fitting with a female thread at each end. It joins two male ends, such as two hoses that each have a male fitting, or a hose and a male-threaded device. The listing gives both ends as 3/4 inch GHT. That is the main fit check. If one of the ends you plan to join is not 3/4 inch GHT male, the coupler will not seat properly, and the listing gives no other size.
The listing says the package includes four spare washers. Washers help the joint seal. Keep a spare set on hand, because a worn or missing washer is a common cause of drips at a hose joint. The listing does not describe the washer material or size beyond the count.
The listing’s dimensions are 3 by 4 by 5 inches, which suggests the coupler is compact. The package weight is 1.6 ounces. Those numbers help you judge storage and hand feel, but they do not replace a physical check of your fittings.
Backflow and chemical use
Hose-end connections can be a route for backflow, which means water moving the wrong way back into the supply. A Colorado State University Extension page says that hose connection backflow prevention devices may provide protection for the system when insecticides, other pesticides, or fertilizers are applied by means of a hose-end spray attachment. That statement is about devices made for the job. A plain coupler is not described as one of those devices, and the Extension page does not say that a coupler provides protection.
The same Extension page says vacuum breaker devices are effective only against back-siphonage. A vacuum breaker helps when pressure drops and water starts to flow backward. It is not described as protection against every backflow condition, and a coupler is not a vacuum breaker.
The EPA Cross-Connection Control Manual from February 2003 includes an installation diagram for a hose bibb vacuum breaker. That diagram is a reference for a backflow device. The manual covers cross-connection control in water systems and does not evaluate consumer couplers. If you apply fertilizer or pesticide through a hose, read the label, check your local water utility’s rules, and ask whether a listed backflow device is needed at your faucet.
The Hourleey listing does not mention a vacuum breaker, a check valve, or any other backflow device. If you need protection for chemical use, the listing does not show that this coupler provides it.
How to check fit before buying
Use this checklist with the listing data. Each step relies on a stated detail, not on a test result.
- Confirm that both ends you plan to join are 3/4 inch male GHT. The listing gives 3/4 inch GHT female threads on both sides.
- Count the pieces you need. The listing says two, so one pack covers two joints.
- Check the washers at each joint. The listing includes four spares.
- Decide whether the joint will carry drinking water, pet water, or chemical sprayer flow. The listing does not address those uses, so do not assume it fits them.
- Check local rules if the coupler sits at an outdoor faucet that feeds a permanent connection.
For joining two garden hoses or a hose and a male-threaded device, the stated fit matches the use. For drinking water, chemical sprayers, or pipe connections, the listing gives no direction.
Who this coupler suits based on the listing
The listing suits a gardener who needs to extend a hose by one length, repair a hose end, or join two hoses that both use 3/4 inch GHT. It is less suited to anyone who needs a pipe-thread connection or backflow protection for sprayers. The listing describes its own use case in these terms, and this review keeps to that scope.
A coupler adds one more joint to a water line. Each joint is a place where a washer can wear. Check the joint after you connect it, and tighten by hand before you use a tool, because over-tightening can damage the washer or the threads. The listing does not give a torque figure, so use gentle hand pressure.
In cold weather, drain the hose and any coupler before freezing temperatures arrive. Trapped water can crack brass or the washer seat. The listing does not mention winter care, so treat that as general advice rather than a seller instruction.
How the listing compares with other coupler types
Couplers come in several materials, including brass, plastic, and aluminum, and some have shutoffs or quick-connect ends. The listing does not compare itself with those options, and this review does not rank it against them. Choose by thread size, material, and whether you want a shutoff at the joint.
Brass is often chosen for threaded connections because the metal holds its shape under repeated tightening. The listing uses that same claim. Plastic couplers can be lighter, but the listing does not describe any plastic part on this coupler beyond the washers.
If you plan a permanent connection, check whether the joint must also meet local rules. A coupler is a fitting, not a complete system, and the listing does not address system design.
What we could not verify
The listing makes several claims that this review could not check against independent sources. These include the solid brass construction, the claim that there is no water leak, the claim that the coupler is heavy duty, and the claim that it is easy to install. The listing does not give test data for these claims, and the two sources do not discuss this coupler.
The listing does not give a pressure rating, a temperature rating, or the exact brass alloy. It does not describe the washer material. Without those details, you cannot judge how the coupler will hold up in freezing weather or under repeated use.
What the sources do not say
The Colorado State University Extension page discusses backflow prevention devices for home sprinkler systems. It does not mention Hourleey, Amazon, couplers, or female to female adapters. It does not say whether a coupler of this type provides backflow protection.
The EPA manual is a technical reference on cross-connection control. It shows a hose bibb vacuum breaker and discusses backflow in general. It does not evaluate consumer couplers, and it does not rate this product. Its diagrams do not replace local code or the device rules set by your water utility.
Neither source tells you whether this coupler will seal at your joint, whether the washers will last a season, or whether the brass is the exact alloy named in the listing. Those questions remain open.
FAQ
Does this coupler fit standard garden hoses?
The listing says it fits US standard 3/4 inch garden hoses. Confirm that both ends you plan to join are 3/4 inch GHT male before you buy.
Is this coupler rated for drinking water?
The listing does not state a drinking water rating. Do not assume it is rated for drinking water, and check the manufacturer’s data before using it for that purpose.
Final notes on the listing
The Hourleey 3/4 Inch Brass Garden Hose Adapter is a two-pack of solid brass female to female couplers with 3/4 inch GHT threads and four spare washers, according to its listing. Its stated use is joining garden hoses and male-threaded devices. Check the thread and the intended use before you buy. If you need a backflow device for chemical sprayers, look for a product whose listing names that protection directly, and confirm it with your water utility.
