3/4in Oil Filter Nipple

The 3/4in Oil Filter Nipple (TRA1034) from TRANS-DAPT is a precision-engineered pipe nipple designed for engine oil filter mounting applications in automotive and industrial systems. This straight-configuration nipple serves as a critical connection point where oil filter adapters, remote filter heads, or cooling lines attach to engine blocks or aftermarket manifolds. Built for reliability in high-temperature, high-pressure environments, this component is essential for builders and technicians who require robust, leak-free oil system connections.

Manufactured from durable steel in a natural (uncoated) finish, the 3/4in Oil Filter Nipple features a 3/4-16 inch NPT (National Pipe Thread) connection on both ends, with a 1-1/4 inch height specification that positions filter mounts at the correct distance from the mounting surface. Steel construction ensures compatibility with standard SAE adapters and resists corrosion in engine bay environments, while the straight nipple design allows direct, in-line connections without elbows or bends. The compact dimensions (2.75 x 1.25 x 3.6 inches) and minimal weight (0.1 lbs) make this nipple ideal for space-constrained engine compartments and custom fuel or oil distribution systems.

This nipple is ideal for custom engine builds, LS swaps, vintage car restorations, and any application requiring a secure, code-compliant oil filter adapter mounting point. Installation is straightforward—thread the nipple into the engine block or manifold boss using appropriate sealing compound or thread tape, then attach your oil filter head or remote mount assembly. Technicians working with non-OEM engine platforms, turbo kits, or modified cooling systems will appreciate the reliable, cost-effective solution this component provides for professional-grade oil system plumbing.
