It enables a secure, leak-proof transition to MNPT threaded connections, handling high pressure and temperature fluctuations with ease. Made from lead-free DZR brass, it offers corrosion resistance and durability. Certified to ASTM F-1960 and F-877 standards, this adapter ensures compatibility with all PEX-A tubing brands. Its expansion fitting design allows for fast, solder-free installation using a PEX expansion tool, making it ideal for professional plumbers and DIY enthusiasts aiming for reliable, long-lasting plumbing solutions.

## Description

SharkBite expansion fittings are designed to work seamlessly with PEX-A hoses and PEX-A expansion rings, ensuring a secure and leak-free connection and providing optimal flow control for your water supply. Cross-linked polyethylene piping is more unyielding to burst pressure, reliable in freezing temperatures, and requires fewer joints due to its superior flexibility. Expansion fittings, especially those used with PEX pipes, are designed to have a smooth interior surface. This design minimizes turbulence and friction to allow full water flow. PEX-A plumbing systems are suitable for pro plumbers and DIY enthusiasts undertaking home improvement projects. SharkBite expansion sleeves fit snugly over the PEX pipe, providing a strong and durable seal that withstands high water pressure and temperature fluctuations ensuring a secure and leak-proof connection for your PEX pipes. SharkBite Expansion manifolds are compatible with all PEX-A tubing from any manufacturer. Expansion fittings are quick and easy to install. Cut pipe to proper length and slide the expansion ring over the PEX-A hose. Use a manual PEX expansion tool, or a cordless PEX expansion tool to insert and hold fitting in place until the expansion ring and tube contracts tightly. The Interior cross-hatch stops the ring from sliding off the pipe to ensure proper and quick installation; No solder or bonding agents required making your plumbing work quicker, reliable and more efficient.

Review: Very well made. They work as they should.
