1/4 in neoprene cord

This 30 ft length of closed-cell neoprene cord is suited to sealing, cushioning and general-purpose gasket work in workshops and light-industrial settings. The round profile and smooth texture make it easy to press into channels or wrap around irregular shapes.

Firmness and temperature range

A 9 to 13 psi rating at 25 percent deflection gives a firm but compliant feel that holds a seal without crushing. The material stays flexible from -40 to 160 Degrees F and meets ASTM D1056 2C3 with good resistance to water, weather, oil and common chemicals.

Compatibility checks

Verify that a 1/4 in diameter fits the groove or gap you intend to fill and that the 16 lb/cu ft density matches the load you expect. Confirm that the 9.2 percent compression set and fair abrasion resistance are acceptable for the cycling frequency and contact surfaces in your application.

Questions about this item

What does the ASTM D1056 2C3 standard specify for this neoprene cord?

The ASTM D1056 2C3 standard defines the material grade for this closed-cell neoprene cord, confirming its density of 16 lb/cu ft, firmness of 9 to 13 psi at 25 percent deflection, and tensile strength of 100 psi.

What diameter hole or channel is needed to fit this 1/4 in neoprene cord?

This cord has a round 1/4 in diameter, so a hole or channel slightly larger than 1/4 in is required for a proper fit; the closed-cell structure resists compression set at 9.2 percent.

How is this neoprene cord installed, and what common mistake should be avoided?

Cut the 30 ft length to size and press the smooth, round cord into the groove or channel; avoid stretching it during installation, as tension can reduce the effective seal and increase compression set over time.
