Ratchet clamp for pipe coupling
12523320 · 2026-01-13 · ·

A pipe coupling includes a coupling band and an elastomeric seal disposed inside the coupling band, ratchet depressions formed on a portion of the coupling band, and a ratchet rod assembly mounted on another portion of the coupling band. The ratchet rod assembly includes a ratchet rod formed with ratchet teeth that interface with the ratchet depressions, such that rotation of the ratchet rod causes the ratchet teeth to progressively advance from one set of the ratchet depressions to another set of the ratchet depressions, which reduces an inner diameter of the elastomeric seal in the coupling band.
