Master oil filter gasket kit

This Master oil filter gasket kit is a service part for the oil filter assembly found in air heaters with oil-fired burners. The gasket kit provides the sealing elements needed to close the filter housing after the filter element has been changed. In an oil system, the filter sits between the tank and the oil pump; it removes particles that could clog the nozzle or damage the pump internals. A proper seal at the filter housing is essential to prevent air ingress (which leads to pump cavitation and erratic firing) and to avoid fuel leaks that pose a fire or environmental hazard. When selecting a gasket kit for this application, the engineer must match the gasket shape, material, and diameter to the specific filter model. The gasket material must be compatible with heating oil – typically a nitrile rubber (Buna-N) or fluoroelastomer (Viton) – though the exact compound is not listed in this kit’s data. During replacement, the old gasket should be inspected for hardening or cracking; the sealing surfaces must be clean and free of old adhesive or debris. Tightening the housing to the correct torque prevents distortion and ensures a leak‑free joint. This kit includes the necessary gaskets for a single filter service. No dimensions, compatibility with specific filter housings, or material details are given in the catalogue entry. The part is referenced under catalogue article 428.379.001 and manufacturer codes 428.379.001 and 4111.116.
