Zoro Select Foam Cord 100 ft

This Zoro Select foam cord is a closed-cell neoprene seal supplied in a 100 ft length with a 5/16 in diameter. The black material carries a density of 16 lb/cu ft and meets ASTM D1056 2C3 grade standard. It suits maintenance, fabrication and shipping teams that need a continuous length for gasketing, cushioning or weather stripping.

Suitable for sealing and padding tasks

This cord suits buyers who need good resistance to water, weather, oil and chemicals across a -40 to 160 Degrees F range. It is not for applications that demand high abrasion resistance or a lower compression set than 9.2 Percent. Buyers who need a different diameter, cell structure or a certified flame rating should look at other materials.

5/16 in diameter closed-cell neoprene

The 5/16 in diameter and closed-cell structure determine whether this cord fits the groove, gap or channel in your assembly. Verify the required cross-section and the 9 to 13 psi firmness at 25 Percent deflection against your design specification before ordering.

Questions about this item

How can I confirm the foam cord is performing correctly once installed?

The cord should compress smoothly under load and return to its original round shape, with a compression set of only 9.2 percent and firmness between 9 to 13 psi at 25 percent deflection.

What comes in the box and what else might I need?

The package contains 100 feet of 5/16-inch diameter black neoprene cord; no extra components are included, so buy cutting tools or adhesive separately if your application requires them.

Which version of this foam cord should I choose for my sealing job?

This single specification meets ASTM D1056 2C3, handles -40 to 160 degrees F, and offers good water, weather, chemical and oil resistance — select it when those ratings match your requirements.
