Raypak 004904F – Pressure Switch Tube Kit – 105A Heaters
If your 105A heater will not prove water flow, shuts down on pressure-related safety, or refuses to fire even though circulation appears normal, the pressure switch tube kit is worth checking early. 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.
This 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.
- Heater will not fire because pressure safety is not proving
- Tube is cracked, brittle, blocked, or disconnected
- Flow-related shutdowns appear during Raypak heater troubleshooting
- Pressure switch seems good but the signal line has failed
What this part does: It carries the pressure signal to the heater pressure switch so the safety circuit can operate correctly.
Compatibility: Designed for Raypak 105A heaters. Confirm with your model number before ordering.
- Part Number: 004904F
- Type: Pressure switch tube kit
- Application: 105A heaters
OEM Value: A genuine Raypak tube kit helps maintain the intended routing and fit in the pressure safety circuit. When the signal line fails, even a new pressure switch will not solve the real problem.
