Water Heater Connector Design

The Apollo APXCSST1834 is a corrugated stainless steel connector built to link hot and cold water lines to a water heater using PEX connections. It suits installers who want a fast, simple hookup without soldering. The 18 in. length provides reach between the tank nipples and the supply lines.

Capacity and Headroom

The connector handles standard residential water heater hookups for both hot and cold lines. Its stainless steel construction resists corrosion from treated water. It runs out of reach when the supply stub-outs sit farther than the 18 in. length allows, requiring a longer connector or additional piping.

Connection Interface Limits

The FNPT end threads onto the water heater MNPT nipples after pipe thread tape is applied and is tightened with pliers. The PEX barb end accepts copper crimp rings, stainless steel pinch clamps or stainless steel sleeves for a secure joint. California Proposition 65 warnings apply because the product contains a listed chemical.

Questions about this item

Will the 18 in. connector reach the existing 3/4 in. PEX lines on my older water heater?

The 18 in. length is designed to connect hot and cold water lines to water heaters using PEX connections, so it should reach typical tank nipples.

How can I confirm the ApolloPEX connector is sealed correctly after installation?

After threading the FNPT end onto the tank with pipe thread tape and securing the PEX side with crimp rings or pinch clamps, pressurise the system and check for leaks at both joints.

Does the box include crimp rings or pinch clamps for the PEX connection?

The connector itself is supplied; copper crimp rings, stainless steel pinch clamps or stainless steel sleeves must be purchased separately to complete the PEX connection.
