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. ## Features - Facilitates seamless transition between 5/8 inch OD PEX tubing and 1/2 inch PEX tubing - Compression fitting ensures a secure and leak-free connection - Suitable for residential and commercial plumbing applications - Durable construction withstands high pressure and temperature variations ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | XFITTING | | Color | Brass | | Connector Type | Adapter | | Item dimensions L x W x H | 4 x 3 x 1 inches | | Material | Metal | | Size | OD 5/8"x1/2" Pex | ## Images ![XFITTING OD compression 5/8 Inch x 1/2 Inch Pex Transition Straight Adapter, 26-5-3=2X, 2 Pieces - Image 1](https://m.media-amazon.com/images/I/61PA1pXw4rL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by M***E on January 30, 2026* Plumber wanted $800 to install two press fittings.
