1" Male Hex Nipple Pipe Fittings, 304 Stainless Steel 1 inch NPT Threaded Pipe Adapter Fittings Equal Nipples Connectors, Male Straight Connector Pipe Fitting (1“, 2pcs)

Did the job. My water pressure is set to about 40psi so not really high in first place, but happy with results. It fit, no redo work, I cranked them down tight and they handled like a champ. I've had them installed for maybe a month now, no leaks and I checked daily for the first week and now i don't even think about it. just be sure to use lots of PTFE on the threads like with any threaded fitting, especially if you're trying to line up your water filter housing (etc), like I was. Price is fair with others out there and quality is also good.

Work very well to hold 2 whole house filters together. I don't have to worry about corrosion.

Real proper NPT thread with proper taper! So easy to use! Love it!

Well built, solid materials

These fittings have an id of about .290 in, so they are every bit as beefy as the 3000psi rated fittings. And they come with plastic thread protectors and have a nice little zip lock bag. How can you go wrong? And to top it off, Amazon delivered the fittings in the early part of their window, which is a rarity these days.

I bought this to connect 2 cables for my bidet. I tried multiple ones from other places and it was not faithfully keeping the pressure well. This one, however was very good and keeping the water pressure without leakage.

Bought the 1" coupling from these guys and am proud to report that the tapered threads perfectly matched the NPT standard. Previously, I had problems with numerous other sellers here on Amazon (Taisher to name one of the larger ones) in achieving a leak-proof connections. I'm heading on the road to my rental 300 mi away to install a water softener and didn't want to run into problems and delays. Neither Home Depot nor Lowe's sell stainless steel fittings like this. I will use these couplings to connect to a stainless bypass valve on a Fleck 5600SXT softener. So needed stainless coupling to bridge over to the normal type of 1" corrugated flex connectors (that are also stainless with dielectric FIP ends). These fittings worked perfectly! Only had to use 5-6 turns of teflon tape and some plumbers paste and tightnen them per the best practices, and sure-enough, I had a perfect, leak-proof seal, right the first time! Definitely recommend this company and hope they grow their product offerings and give Taishler's a run for market dominance here on Amazon!

This item is actually stainless steel like it says it is

It was worth the wait. Great product.

Stainless steel as advertised, NPT threading, heft. Very pleased.
