This flex connector features a 3/4-inch Push-to-Connect (PTC) fitting on one end and a 1-inch FIP (Female Iron Pipe) threaded fitting on the other end, with a total length of 18 inches. The 3/4-inch PTC side accepts 3/4-inch OD tubing (CPVC, PEX, or copper) with a simple push-in connection, while the 1-inch FIP end threads directly onto standard 1-inch male pipe threads—making it ideal for connecting water heaters, softeners, and main supply lines.

Yes, this 18-inch Stainless Steel Flex Connector is constructed with lead-free brass fittings and a corrosion-resistant braided stainless steel outer sheath, meeting the low-lead requirements of the Safe Drinking Water Act (SDWA). It is designed and certified for use with potable drinking water systems, and the internal components comply with NSF/ANSI 61 standards for drinking water system components.

This stainless steel flex connector is rated for a maximum working pressure of up to 200 PSI and a maximum temperature of 200°F (93°C), making it suitable for both cold and hot water applications, including water heater connections. The braided stainless steel jacket provides burst protection and resists kinking, ensuring a reliable, long-lasting connection throughout the life of your plumbing installation.

No special tools are required for the 3/4-inch PTC side—simply cut the tubing squarely, deburr the edge, and push it firmly into the fitting until it seats against the internal stop (typically about 1 inch of insertion depth). The 1-inch FIP side requires standard plumbing tools; wrap the male threads with PTFE (Teflon) tape 2–3 times before hand-tightening, then use a wrench to tighten an additional 1–2 turns. Avoid overtightening to prevent damage to the fitting.

This flex connector is specifically designed for whole-house water treatment installations, including connecting water softeners, whole-house filtration systems, tankless and tank-style water heaters, and main water supply lines. The 18-inch length provides sufficient flexibility to absorb minor misalignments between equipment and supply lines, reducing installation stress and making future service or replacement significantly easier.
