Grease Fitting 1/4-28, 90 Degrees Angle
The Grease Fitting 1/4-28, 90 Degrees Angle is a premium-quality lubrication component designed to deliver grease to hard-to-reach areas in machinery and equipment. Commonly referred to as a Zerk fitting, this 90-degree angled fitting with a 1/4"-28 taper thread ensures efficient lubrication for bearings and moving parts, enhancing equipment longevity and performance. Ideal for automotive, agricultural, and industrial applications, this fitting is crafted for durability and ease of installation.
Key Features
90-Degree Angled Design: The 90-degree angle allows easy access to tight or confined spaces, making it perfect for applications where straight fittings are impractical.
Standard 1/4"-28 Taper Thread: Conforms to SAE-LT specifications with a 1/4"-28 UNF-3B thread, ensuring compatibility with most grease guns and equipment. Recommended for installation into straight-threaded holes with a modified maximum minor diameter of 0.2151” for 75% thread height.
Durable Construction: Made from zinc-plated steel for corrosion resistance, withstanding harsh environments and exceeding 72-hour salt spray tests. Stainless steel options are available for severe corrosive conditions.
Dirt-Excluding Ball Check: Features a ball check valve to prevent dirt ingress and ensure grease flows into the bearing, maintaining clean and efficient lubrication.
High-Pressure Performance: Rated for relief pressures up to 6,000 PSI, providing reliable performance under demanding conditions.
Easy Installation: Threaded design allows for quick installation using a wrench or pliers, with a 3/8" hex size for secure fastening.
Why Choose the 1/4-28 90-Degree Grease Fitting?
This grease fitting is engineered for professionals and DIY enthusiasts who need reliable lubrication solutions for complex machinery. Its 90-degree angle simplifies greasing in tight spaces, such as on cars, trucks, trailers, or industrial equipment, where straight fittings are challenging to access. The zinc-plated steel construction ensures durability and resistance to rust, while the ball check valve maintains clean lubrication channels. Compatible with high-performance grease couplers like LockNLube, this fitting supports efficient, leak-free greasing, reducing waste and downtime.

Usage and Maintenance Tips
Installation: Clean the receiving hole and thread the fitting into a 1/4"-28 UNF-3B straight-threaded hole using a wrench or pliers. Ensure a tight seal to prevent leaks.
Usage: Use with a compatible grease gun (e.g., LockNLube coupler for secure, leak-free greasing). Apply grease until resistance is felt, indicating the bearing is filled.
Cleaning: Use a grease fitting cleaner with a flexible hose for blocked fittings to restore flow.
Storage: Store in a dry environment to prevent corrosion, especially for non-stainless steel fittings.
Safety: Wear protective eyewear during installation and greasing to avoid injury from high-pressure grease. Do not exceed the maximum relief pressure.
The Grease Fitting 1/4-28, 90 Degrees Angle is a reliable, high-performance component that simplifies lubrication in challenging applications. Its durable construction, industry-standard threading, and angled design make it an essential tool for maintaining machinery and ensuring optimal performance across various industries.
