Our ultra-flexible ¾” large diameter connectors are designed for gas appliances with large BTU requirements (up to 290,900 BTU/hour) like our tankless and commercial water heaters, boilers, furnaces, and pool heaters. Factory assembled to eliminate on-site pipe cutting, threading and assembly; our connectors increase the efficiency of the installation, saving you time and money.
Our Gas Flex is sized accordingly for the BTU's of our units (Up to 290,000 BTU's) and is unlike other yellow gas flex one can buy at a Hardware store. Do not try to connect your existing gas flex to the Rinnai Units.
Greater depth and number of corrugations to withstand greater torque and bend cycles. High tensile strength stainless steel is less susceptible to work hardening.
Torsion Test - per ANSI Z21.24, withstands more than 15 applications of 90 degree twists in alternate directions without leakage or damage to the tubing or coating.
Bend Test - per ANSI Z21.24, withstands more than 30 bends without leakage or damage to tubing or coating.
