OURU 100Pcs 1/4″-28 SAE Grease Fittings Kit
The OURU kit provides a large set of straight 1/4″ zerk grease fittings, plus caps and an 8mm wrench. The fittings are made of galvanized steel for corrosion resistance in harsh outdoor environments, making them a strong choice for farm, workshop, or construction equipment. The kit’s straightforward design allows direct connection to a grease gun and simple replacement of worn fittings without disassembly, which helps minimize maintenance downtime.
Best for: buyers who need a bulk supply of replacements and want corrosion resistance for exterior equipment. The inclusion of caps and a wrench adds value for quick field maintenance. Caution: bulk components can be more challenging to organize without a storage system; rely on the included caps and case to keep fittings in order.
AKEOIL 60Pcs SAE & NPT Grease Fittings Kit
This kit combines 1/4″-28 SAE and 1/8″-27 NPT grease fittings in straight, 45°, and 90° angles.

The fittings are rated for high-pressure use, supporting demanding industrial or automotive lubrication tasks where seals must hold under pressure.
Best for: users who require stainless steel corrosion resistance and high-pressure performance for heavy-duty applications. Caution: stainless variants can be more expensive than standard steel counterparts, so evaluate the budget against your expected duty cycle.
Buying Guide
What to consider when choosing 1/4-20 grease fittings
- Thread type and size: Ensure compatibility with your grease gun ports and machines. SAE 1/4″-28 is the most common for automotive and industrial use, while NPT variants appear in some equipment.
- Angle options: Straight, 45°, and 90° fittings reach different lubrication points. Angled fittings help access restricted spaces without disassembly.
- Material and finish: Galvanized steel offers corrosion resistance for outdoor or dusty environments. Stainless steel improves rust resistance in challenging climates but may come at a higher cost.
- Durability and reuse: Zinc plating and precision threads reduce leaks and wear. Check for check valves or seals that prevent dirt ingress when not in use.
- Storage and organization: Kits with labeled compartments or protective caps simplify selection and maintain order in busy workspaces.
Frequently Asked Questions
- What is the difference between SAE and NPT grease fittings?
SAE fittings use standard straight-threaded designs common in automotive systems, while NPT fittings use pipe-thread standards common in some industrial equipment. Ensure your ports match the thread type. - Why choose angled fittings?
Angled fittings reach tight or side-access lubrication points that straight fittings cannot access, reducing disassembly time. - Are caps important for grease fittings?
Caps protect the threads from dust, moisture, and debris, extending fit longevity. - Is stainless steel worth it for grease fittings?
Stainless steel offers superior corrosion resistance and durability in harsh environments, making it suitable for long-term outdoor use or saline settings. - How many fittings should I buy?
If you service multiple machines, a larger kit minimizes trips to replacement parts. For a single vehicle, a smaller, targeted selection may suffice. - Can I mix different brands in one service kit?
Yes, as long as thread sizes and angles match your equipment, combined kits can provide broader coverage.
