Raypak 53/53A/55A/105A/151/153/155A Orifice [Nat] [MV] (003901F)

The Raypak burner orifice is designed for compatible 53, 53A, 55A, 105A, 151, 153, and 155A heater applications using natural gas in an MV configuration. A burner orifice is useful because it helps meter gas flow correctly for the supported fuel type, supporting cleaner burner performance and more dependable heater operation.

This replacement is especially useful when the original orifice is clogged, damaged, or no longer matched to the supported natural-gas application. Matching the correct natural-gas MV orifice helps preserve intended combustion behavior and setup accuracy.

The 003901F is a practical service part when a compatible Raypak heater needs a natural-gas MV burner orifice to restore proper fuel-delivery support.
