Kromschroder Spare part kit 03089205

Kromschroder spare part kit 03089205 is a service kit for GDJ 40 and GIK 40 gas pressure regulators, with a nominal diameter of 40 mm. It includes diaphragms, O-rings, and body gaskets for scheduled maintenance. This kit is compatible with GDJ 40R04-0Z and GIK 40R02-5 regulators. It is designed to restore tightness and accuracy without replacing the entire regulator.

Parts of this type are selected by matching the regulator series and nominal diameter. Before ordering, confirm the regulator model and size, as internal clearances and seal dimensions are specific. Installation should follow the manufacturer's technical documentation, ensuring mating surfaces are clean. The kit is intended for use during scheduled maintenance or after wear-related issues.

Worn seals and diaphragms in regulators of this kind can cause unstable outlet pressure, gas leaks, or intermittent burner operation. Symptoms may include difficulty maintaining set pressure or gas escaping through the impulse tube. Regular inspection of these components is recommended to prevent emergency shutdowns.
