Great bulk buy

I run a small auto shop and we go through these regularly. This pack lasts us a few months and ensures all our hoses stay tight. No complaints.

Stopped the hissing noise

My air hose was leaking badly at the connection point. Swapped out the old O-ring with one of these and the hiss is gone. Highly recommend keeping a pack in the toolbox.

Essential maintenance part

If you use pneumatic tools, you need these. They are cheap insurance against losing pressure. The material seems resistant to oil which is a plus.

Perfect fit for my compressor

These gaskets fit my Type C connectors perfectly. The rubber feels durable and stops the air leak immediately. Great value for the price.

Good quality seals

Bought these to replace worn-out rings on my shop vac attachments. They work well, though I wish the pack came with a few more sizes just in case.

Decent but stiff initially

They work fine once installed, but the rubber was a bit stiff out of the package. Had to warm them up slightly to get a good seal without forcing the connector.

5 FAQ

Q: How do I know if I need to replace my current gasket?

A: Signs that you need a replacement include audible hissing at the connection point, difficulty locking the connector, or visible cracks and flattening on the existing rubber ring.

Q: Will these fit standard industrial Type C couplers?

A: Yes, these gaskets are designed specifically to fit standard industrial Type C quick connect couplers commonly used in pneumatic applications.

Q: Are these resistant to synthetic compressor oil?

A: Absolutely. The Nitrile Rubber (NBR) material used in these gaskets offers excellent resistance to petroleum-based oils and synthetic lubricants.

Q: What is the shelf life of these rubber gaskets?

A: When stored in a cool, dry place away from direct sunlight and ozone sources, these gaskets have a shelf life of approximately 5 to 7 years.

Q: Can I use these for water hoses or just air?

A: While primarily designed for air systems, they can handle water applications within the specified temperature and pressure limits. However, for dedicated water lines, EPDM rubber is often recommended for long-term UV resistance.
