Product details

The Raypak 003903F is the natural gas pilot orifice for Raypak 53A, 53B, 055A, 055B and 105A IID electronic ignition pool heaters.

What it does

The pilot orifice is a small fitting in the pilot assembly that meters the gas flowing to the pilot flame. A blocked or worn orifice can cause a weak or unstable pilot, so it is a routine replacement part when a pilot will not stay lit.

Fit and compatibility

The orifice is listed for the Raypak 53A, 53B, 055A, 055B and 105A IID pool heaters and is the natural gas version. Heaters set up for propane use the propane orifice, Raypak 004308F. Confirm the model and fuel type on your heater rating plate before you order.

Before you order

This listing is the orifice only and does not include the pilot assembly or the ignition control.
