## Description

Upgrade your plumbing system with the XFITTING OD Compression 5/8 Inch x 1/2 Inch Pex Transition Straight Adapter. This high-quality adapter facilitates a seamless transition between 5/8 inch outer diameter (OD) PEX tubing and 1/2 inch PEX tubing, ensuring a secure and leak-free connection. Crafted with precision and durability in mind, this adapter is ideal for residential and commercial plumbing applications. Engineered to withstand high pressure and temperature variations, it offers reliability and peace of mind for all your plumbing needs.

Review: Good quality - Plumber wanted $800 to install two press fittings. This was a better deal. Great quality, easy install, perfect fit.
Review: Great for extending pipes behind walls in home modifications - I just refuse to use Sharkbites behind walls and rely on a tiny oring to hold back water over decades behind an interior wall. I'm also not a plumber so I don't / can't sweat fitting to copper pipes. The compression fitting makes a great connection to the existing copper pipe and the PEX transition, when used properly with PEX crimp rings, should provide a reliable, leak-free connection.
