High-Temperature Silicone O-Ring Kit (Size #007)
The steam boiler probes and hose unions rely on silicone O-rings that degrade after 2-4 years of thermal cycling. This loss of elasticity (compression set) allows high-pressure steam to bypass the fitting, manifesting as an internal leak. Replacing these O-rings restores the pressurized seal of the steam circuit.
