Product Description

The Merit Brass class 150 coupling is a stainless steel 304 cast pipe fitting with female National Pipe Taper (NPT) threads for connecting and extending pipes going in the same direction. Made of stainless steel 304, the low carbon content of this fitting ensures higher corrosion resistance than 302 grade steel. The coupling has NPT threads for creating tighter seals than straight threads. This class 150 fitting meets standards ANSI B1.20.1 and ISO 49 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).

Merit Brass manufactures pipe nipples following ISO 9001 standards for quality assurance. Family-owned since 1937, the company is based in Cleveland, OH. Merit Brass distributes pipe fittings to the United States and Canada.

5.0 out of 5 stars Very high quality coupling! November 29, 2012
Size Name:1/2"|Verified Purchase
After buying a 1/2 to 1/2 coupler from a local hardware store that was hideous, bulky, and prevented me from attaching my showerhead securely (due to the bulk), I was very pleased to receive this one. It's very high quality, has a very clean finish, and is quite thin, which allowed me to fully secure it to the shower pipe embedded in my wall. Great.
I'll try to upload a pic showing the crappy hardware store one compared to this one... really obvious difference in quality!

5.0 out of 5 stars Exactly what I needed February 11, 2014
Size Name:1/2"|Verified Purchase
I looked all over the hardware stores locally to find this and no one had a female-to-female connector for the shower head. Hoooray Amazon! I scratched it up slightly when installing, but I was using metal on metal with the pipe wrench so that's to be expected. Heavy duty little thing.

5.0 out of 5 stars Seems adequate May 13, 2011
Size Name:1/8"|Verified Purchase
The fitting looks well made. Note that the photo (not mine) is actually of a similar fitting in a larger size, perhaps 1" npt (which makes the walls look thin).

The fitting is about 1" long by 1/2" in diameter. The bore is a little over 1/4", so the walls (including the threads) are nearly 1/8" thick

5.0 out of 5 stars good quality March 7, 2014

Size Name:3/4"|Verified Purchase
A cheaper alternative to brass. But will resist corrosion just the same. I have replaced all galvonized fittings in my plumbing system with these stainless for half the cost of brass.

This works perfectly if you are doing a mash tun build to connect a 1/2" NPT pipe nipple to a 1/2" NPT male bazooka screen.

Fits the 1/2 inch threading needed to put a bazooka wire mesh for my brew kettle. Just wash it before use.

5.0 out of 5 stars Right when I needed them. February 23, 2014
Size Name:1/4"|Verified Purchase
I use these couplings to put two air lines together and I have switched to steel for the strength because one day we were out in the garage and pop air blowing straight across the room. Steel for me no longer going to use brass for this type of connection and stainless was just a perk that made the decision all the more easy.

5.0 out of 5 stars One item at a fare price.
This is a dodgy time to be buying kit. All of a sudden all the bits have changed from MPT to NPT. the MPT bits have shot up in price. I was lucky to find this item at a fare price.
