Loc-Line - 32093 Coolant Hose Component, Acetal Copolymer, Valve, 1/2 Hose ID, 1/2 NPT Female, 100 PSI (Pack of 2)

The title states 100 PSI which is misleading. The 1/2 NPT connection can handle 100 PSI but the in-line valve can only handle 20 PSI. I had no issue sealing the 1/2 NPT connection but there is nothing you can do if the ball valve leaks. RV water pumps keep 40 to 60 PSI of pressure which is too much for the in-line valves 20 PSI limit. As a result the valve will leak, dripping a drop every minute or so. I should have read the packaging before spending an hour crawling on rocks to attach these valves.

Junk, I put them on my low water drains on my rv and they both started leaking immediately. Went back with original caps

Installed on my low point drains on my RV travel trailer. It seemed like a good idea but both valves leak badly. I had to remove these valves and go back to the original end caps.

Replaced my camper’s low level line drain caps. Winterizing my camper will be simpler and quicker easily reached from the side vice laying under the caper with two wrenches and splashing water on me. Wish they were available singly, also. I want to replace my freshwater drain cap too but don’t need to keep a spare valve,

works pretty good, quite stiff and hard to open or close all the way, would prefer brass but they are a decent valve for the $

Just what I needed, worked great

I installed these on the low-point drains of my RV and they immediately began dripping, and that was before the pump was turned on (e.g., just gravity - no pressure). I sent them back.

My travel trailer came with end caps on the Low Point plumbing drains . These required two wrenches to remove (one to hold fitting and one to unscrew cap) and they’re hard to reach under trailer. I tried PVC valves I bought at Home Depot but they leaked. Read reviews from others who said they work good and so far, they’re right! No leaks and very convenient. Addendum: After almost a year of use at least one of the two has a small leak. I’m going to try some lubricant on the ball valve to see if that helps seal when closed. Also, I covered the hanging low point pipes and valves to protect against road grime that may possibly interfere with ball valve. We’ll see if that takes care of leak.

Bought these for my RV low point drains. They work great!! I was tired of taking caps off the low point drains and having to fight with them all the time. Bought these and installed them, now all I have to do is turn a valve and no more fighting with the caps with the RV low point drains. Very Happy with these!

I fear these will break as they are entirely plastic. They work but I also wish they werent such strange color combinations
