🦈 SharkBite UC094LFA 1SB X 1FNPT PEX Adapter - Premium Brass Connector, 1" x 1" Size Review

This adapter is a lifesaver for threaded pipes in any plumbing project. It fits perfectly and works great, making installation quick and easy. The compact design makes it very convenient for use in tight spaces. The only downside is that it can be a bit pricey compared to other options. Overall, a great tool for anyone doing plumbing work at home.

Perfect fit. The surface was smooth with no sharp edges. The connection mates seamlessly with both PEX pipe and male connector fittings.

I bought 2 of these fittings to connect an iSpring WSP-100 spin down filter to my 1" PEX tubing. Not sure if it's the fittings or the filter but I can't get them to leak. I used 4 layers of water tape and some thick pipe grout and tightened the fittings until they fell off and both ends stand still slowly It looks like the filter or those fittings don't have enough taper They both may be within manufacturers tolerances but both have one low taper of that tolerance, which means I have a problem.
