6-Pack 5/16 Inch PEX Brass Coupling Fittings - Straight Connectors For Plumbing & RV Repairs

About This Product

For DIY plumbers or RV owners, these 5/16 inch PEX brass couplings are seriously handy little connectors that make repairs and installations so much easier. The pack of six gives you plenty to work with, whether you're fixing existing plumbing or building new systems. The solid brass construction feels substantial and durable - these aren't flimsy plastic fittings that might crack under pressure. What's really nice is the barb design - the barbs are deep enough to grip the PEX tubing securely without being so aggressive that you need special tools or heat to get them on. They're rated for up to 200 PSI and temperatures to 200??F, which covers most residential and RV applications. The 1.97-inch overall length gives you good working space, and the G1/4 threads are compatible with standard PEX systems. Installation is straightforward - just push the fitting into the PEX tubing and secure with a clamp, and you've got a leak-free connection that'll last. They're perfect for connecting two pieces of PEX line, repairing damaged sections, or building custom plumbing setups for homes, RVs, or even hydronic heating systems. For the price, you're getting professional-quality fittings that make plumbing projects much less intimidating.
