Trico 37033 Grease Fitting Washer 1/8 Npt Buna-n Green

Product Description

The TRICO 37033 is a 1/8 NPT grease fitting washer designed to seat and seal at the base of standard zerk-style grease fittings. Made from Buna-N elastomer, this washer provides a reliable compression seal that resists petroleum-based greases and common lubricants. Each package contains 10 washers. The Buna-N compound offers good resistance to oil and grease, making it a practical choice for lubrication fittings in industrial and mechanical maintenance applications. Licensed mechanics, millwrights, and lube technicians keep these on hand for fitting replacement and resealing work.

These washers are used wherever 1/8 NPT grease fittings are installed, including bearing housings, chassis lubrication points, conveyor systems, and general plant machinery. They are a standard consumable for any shop performing preventive maintenance on equipment with grease-lubricated components. The green color aids in visual identification when sorting fitting hardware on the job.

Key Features

Compatibility

Designed for use with standard 1/8 NPT grease fittings across industrial and mechanical maintenance applications.

Installation Notes

Millwrights, lube technicians, and maintenance mechanics typically install these washers during grease fitting replacement or resealing. De-energize and lock out equipment before servicing any lubrication point. Seat the washer at the fitting base before threading the fitting into the port. Do not overtighten fittings, as Buna-N seals can be cut or extruded under excessive torque.
