Kromschroder Spare filter and O-ring 74923284

The Kromschroder spare filter and O-ring set, SKU 74923284, includes one filter element and one sealing O-ring. It is designed for use with GFK 15/20 and GFK 40/50 gas valve or regulator assemblies. The filter protects downstream components from particulate contamination, while the O-ring ensures a gas-tight seal. This set is not interchangeable with other models and is intended as a routine replacement item during service.

Parts of this type are selected by matching the exact assembly model and manufacturer part numbers. Before ordering, confirm the existing assembly's part numbers correspond to the listed codes (74923284 and 624.385.004). During installation, clean mating surfaces and lightly lubricate the O-ring with compatible grease if recommended. The set includes only the filter and O-ring; other sealing elements must be sourced separately.

When such filter and O-ring sets fail, symptoms may include gas leaks at the connection point, pressure drop across the filter, or contamination of downstream components. Check for visible damage or wear on the O-ring and clogging of the filter element. Replace the set at specified intervals or sooner if pressure drop is detected.
