Grease Fitting

The BERT TRANSMISSIONS Grease Fitting (Part Number 310) is a straight-design lubrication fitting engineered for bellhousing and drivetrain applications in high-performance and restoration automotive work. This 1/4-28 inch thread fitting supplies grease directly to critical pivot points and bearing surfaces where manual lubrication intervals demand precision and reliability. The zinc oxide coating provides corrosion resistance in both street and off-road environments, ensuring consistent performance across seasonal temperature swings.

Manufactured from steel with a zinc oxide protective finish, this grease fitting resists salt air corrosion and brake fluid contact degradation common in transmission bell housings. The straight configuration eliminates angled approaches—critical when working in tight engine bay layouts where space is at a premium. The 1/4-28 thread pitch is a standard specification for BERT bellhousing blocks and adapters, ensuring proper seating without cross-threading. Weighing only 0.02 lbs, it adds negligible mass while handling full-pressure grease gun applications without stripping or leaking.

Buyers restoring classic transmissions, building custom bellhousing assemblies, or servicing drag racing powerplants rely on proper grease fitting selection to prevent premature wear at the input shaft seal, clutch pilot bearing, and bellhousing bushing interfaces. This fitting is commonly purchased as part of bellhousing overhauls, transmission adapter kits, or routine maintenance supplies for shops running high-mileage performance vehicles. Each unit is sold individually, allowing builders to replace fittings one at a time or stock spares for service intervals.
