For a better seal in low-pressure applications, such as hydraulic return lines and oil drain plugs, these O-rings are softer than standard Buna-N O-rings.

Tested to meet ASTM E595, a standard used by NASA, these O-rings give off almost no volatile emissions that could damage sensitive electronics, even in a vacuum. They’re softer than standard Viton®, so they better conform to irregular surfaces.

Softer than standard silicone O-rings, these O-rings form a better seal in enclosures, reservoirs, and other low-pressure equipment. They withstand temperatures up to 400° F or higher. Also known as Boss O-rings, they’re made for tube fittings with a straight-thread connection.

This cord stock is softer and creates a better seal in low-pressure applications than standard Buna-N cord stock.

This cord stock is softer and creates a better seal than standard silicone cord stock in low-pressure applications up to 400° F.
