Male-Female Shower Arm Extension Pipe Guide
As an Amazon Associate we earn from qualifying purchases. Details
A male-female extension pipe adds a short length between the shower arm and the shower head, so the head sits further from the wall. The four fittings below are short G1/2 male-to-female extenders, and each listing gives a length, a thread size and a material. Listing figures are shown as each seller states them, checked on 18 October 2026. Several of these listings give conflicting material or pack counts, so read the product page before you buy.
Quick answer: choose the length that moves the head to the distance you need, then check the material and pack size. The 35 mm stainless steel fitting is the longest in this set. The 20 mm fittings are the shortest. If the listing does not give a length and a G1/2 thread, skip it.

How we chose these four
We kept fittings where the listing names a G1/2 male-to-female extension in its title or specification, and that is sold as a pipe or nipple for a shower. Each of the four is a new pick checked on 18 October 2026. We did not test any fitting, and nothing below reports personal use.
- Length: three of the four are 20 mm, and one is 35 mm.
- Material: the listings give brass, copper or stainless steel. Two of the four give conflicting materials across the listing.
- Pack: the M METERXITY listing gives 3 in the title and 4 in the specification and bullets.
1. Vin Beauty 4-Pack Brass Coupler
The Vin Beauty set is four 20 mm couplers in a G1/2 male-to-female thread. The specification table gives the material as brass and the colour as brass, while the title says copper. The bullets describe a gold finish. The listing says the fittings can be used for gas appliances as well as shower heads. The item weighs 4.64 ounces, and the listing gives item dimensions of 0.39 by 0.39 by 0.79 inches. The listing gives no thread-seal tape.
2. Awclub 3-Pack Brass Nipple
The Awclub three-pack is listed at 20 mm, or 0.79 inch, long, with a 26 mm (1.02-inch) diameter and a 12 mm (0.47-inch) hex width. The thread length is 10 mm (0.39 inch). The title and bullets say brass, but the specification table gives copper for both the material and the colour. The listing includes PTFE thread-seal tape and says to wrap it five to eight turns before fitting. It weighs 3.68 ounces.
3. Awclub 2-Pack Stainless Nipple
The Awclub stainless nipple is the longest in this set at 35 mm, or 1.38 inches, with a 25 mm (0.98-inch) threaded section. It is 304 stainless steel, and the listing gives the same 26 mm diameter and 12 mm hex width as the brass Awclub pack. The pack has two pieces and includes PTFE tape. It weighs 3.84 ounces. The listing says the stainless steel is corrosion resistant, and it does not give a wall thickness.
4. M METERXITY Brass Adapter
The M METERXITY adapter is brass, with a 20 mm (0.79-inch) height and a 26 by 20 mm diameter and height. The title says it is a 3-pack, but the specification table and the bullets both say the package holds four pipe adapters and one roll of sealing tape. The listing says to wrap five to eight turns of tape before installing the pipe, and to use a 12 mm hexagonal wrench.
Worked example: how far does a stack of fittings move the head?
Take the 35 mm Awclub stainless nipple, which the listing gives as 1.38 inches. If you need the head to sit about 1.6 inches from the arm, a single 35 mm nipple falls short by 0.22 inch. Two of the 20 mm brass fittings give 40 mm, or about 1.57 inches, which is closer to the target. The listings do not describe stacking two fittings, so check the joint with a plumber before you rely on it.
The threaded part also matters. The 35 mm stainless nipple has a 25 mm (0.98-inch) threaded section, so about 10 mm of its body is not threaded. The 20 mm Awclub brass nipple has a 10 mm (0.39-inch) threaded section. Using the threaded lengths as the grip, the stainless nipple has 15 mm more thread than the brass one.
What the listings do not say
None of the four listings gives a test result for pressure, leaks or corrosion over time. The material conflicts between the title, the specification table and the bullets mean you cannot be sure of the metal in two of the four fittings. The M METERXITY pack count conflicts between the title and the body. The listings do not give a maximum pressure rating for any fitting. Where a listing includes tape, it says to wrap five to eight turns around the threads before fitting.
Frequently asked questions

The Awclub stainless nipple is the longest at 35 mm, or 1.38 inches. The three 20 mm fittings are 0.79 inch long.
Is the brass fitting actually brass or copper?
The Vin Beauty and Awclub 3-pack listings give copper in at least one place and brass in another. The M METERXITY listing gives brass throughout. Check the material on the product page before you buy.
Do these fittings include thread tape?
The two Awclub listings and the M METERXITY listing include PTFE thread-seal tape. The Vin Beauty listing does not mention tape.
How many pieces are in each pack?
The Vin Beauty pack has four pieces, the Awclub brass pack has three, the Awclub stainless pack has two, and the M METERXITY listing gives 3 in the title but 4 in the body. Count the pieces in the box before you assume a figure.
Can I use these on a bidet or a tap?
The Awclub listings describe use for bathing arms, body nozzles, outdoor pipes and swimming pools, and the Vin Beauty listing mentions gas appliances. The Vin Beauty listing also names taps and tubs. None of the listings names a bidet, so check the thread and the pressure on your fixture first.
Conclusion
For a short extension, the 20 mm brass fittings from Vin Beauty, Awclub and M METERXITY each give 0.79 inch. For a longer one, the Awclub stainless nipple gives 1.38 inches in 304 stainless steel. The M METERXITY and Awclub brass listings both include tape. Read the material and the pack count on each product page before you buy, because the listings give conflicting figures.
