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 valve's 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.

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.

I fear these will break as they are entirely plastic. They work but I also wish they weren't such strange color combinations

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 $

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,
