The FLUIDMASTER pro1h18 is a braided stainless steel water heater supply connector designed for residential and light commercial water heater installations. It features a tough polymer core encased in braided stainless steel wire, delivering reliable burst resistance and long service life. Both end fittings are 3/4-inch female threaded (FPT) with nickel plated brass construction. The connector is lead-free, meeting modern plumbing code requirements. At 18 inches in length, it suits standard water heater rough-in dimensions. Licensed plumbers and qualified installers rely on this connector for code-compliant water heater replacements and new installations.
This connector is intended for water heater supply line applications where a 3/4-inch FPT x 3/4-inch FPT connection is required. The 18-inch length accommodates typical clearances between a shutoff valve and the cold-inlet or hot-outlet port on residential tank water heaters. The braided stainless steel outer jacket provides mechanical protection against abrasion and accidental damage in utility areas and equipment rooms.
Designed as an OEM-style replacement or new-installation supply connector for residential and light commercial tank water heaters requiring a 3/4-inch female threaded inlet and outlet connection.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the cold water supply and drain pressure from the line before disconnecting any existing connector. Hand-tighten fittings first, then use a wrench for a snug, leak-free seal — do not overtighten, as this can damage the polymer core or thread seating. Inspect the connection for leaks after restoring water pressure before returning the system to service.
