A cracked or blocked tube can break the signal to the pressure switch and make a simple safety-line problem look like a bad switch or flow issue elsewhere.\u003c\/p\u003e\u003cp\u003eThis kit provides the tubing used to carry pressure from the heater water side to the pressure switch on compatible 105A heaters. When the tube is brittle, kinked, leaking, or disconnected, the switch may not read correctly and the heater may shut down or never start. Replacing it restores the pressure signal path the safety circuit depends on.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeater will not fire because pressure safety is not proving\u003c\/li\u003e\n\u003cli\u003eTube is cracked, brittle, blocked, or disconnected\u003c\/li\u003e\n\u003cli\u003eFlow-related shutdowns appear during Raypak heater troubleshooting\u003c\/li\u003e\n\u003cli\u003ePressure switch seems good but the signal line has failed\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It carries the pressure signal to the heater pressure switch so the safety circuit can operate correctly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Raypak 105A heaters.
