Meet the Plumb Pak 3/4 in. FIP x 3/4 in. FIP 18 in. Stainless Steel Water Heater Supply Connector — a purpose-built, durable link designed for reliable hot-water delivery in homes. With an 18-inch length, it provides flexible routing around valves, studs, and fittings while maintaining a clean, professional install between your water heater and shut-off valve.
Why choose stainless steel for your water heater line? Stainless steel delivers robust corrosion resistance in hot-water environments, reducing the risk of mineral buildup and leaks over time. Combined with lead-free construction, this connector helps protect your drinking water while delivering steady performance season after season.

Ends: 3/4 in. FIP on both sides — creates secure, leak-resistant connections to standard 3/4 in. piping fittings common on water heaters and shut-off valves.
-
Length: 18 inches — long enough to simplify installation and routing without stressing connections.
-
Material: Stainless steel — built for durability under high-temperature hot water and mineral-rich environments.
-

Ideal use scenarios
- Replacing aged or leaking supply lines to water heaters in single-family homes, townhomes, or apartments.
- Retrofits during appliance upgrades where a longer, more durable connection is beneficial.
- New installations where a clean, corrosion-resistant feed from the shut-off valve to the heater is required.
Installation tips
- Shut off the cold-water supply and relieve system pressure before disconnecting the existing line.
- Apply an appropriate thread sealant to male threads if required by your fittings, then thread onto the 3/4 in. FIP ends. Tighten with a wrench to a snug, leak-free fit—avoid overtightening.
- After installation, slowly turn the water back on and check for leaks at both ends. If a leak appears, tighten slightly and recheck.
