Apollo FSBCSST34F18 3/4 in. Push-to-Connect x 3/4 in. Female Pipe Thread x 18 accessory

Water heater connector with push-to-connect end

The Apollo FSBCSST34F18 is a corrugated stainless steel connector built for hot and cold water lines on residential water heaters. One end carries a 3/4 in. female pipe thread that screws onto the tank nipples after tape is applied. The opposite end uses a push-to-connect fitting that accepts copper, PEX or CPVC pipe without soldering or crimping.

Corrugated stainless steel body

The flexible corrugated steel tube absorbs minor misalignment and vibration while resisting corrosion from treated water. The FNPT side seals with standard thread tape and a wrench, while the push-to-connect side locks on with a simple push and releases with a tool when changes are needed. Both joints are designed for repeated thermal cycling without leaking.

Prop 65 chemical warning and installation scope

California Proposition 65 notices indicate the product contains chemicals linked to cancer and reproductive harm, so installers should follow safe-handling practices. The connector is intended only for water heater hook-ups using the listed pipe materials; it does not suit gas lines, high-pressure mains or other plumbing circuits. Buyers needing different lengths, end configurations or non-metallic tubing must select another part.
