Compression Spring #128, 31/32"x3-3/4"

Compression Spring #128, 31/32"x3-3/4"

A long compression spring designed for controlled resistance and dependable rebound, the 18639 Compression Spring (#128) is built from durable spring steel to provide consistent compression performance in mechanical assemblies and repair applications. With a 31/32" diameter and 3-3/4" length, this spring allows extended travel while maintaining reliable return force. It’s made to compress under pressure and bounce back to shape—because a spring that stays compressed has clearly lost interest in doing its job.
