COUPLING & REPAIR

Style 440 Joint Harness 

Dresser Joint Harnesses are used in conjunction with seal-only couplings to prevent pipe pullout. Standard Style 440 harness restraint consists of steel tie-bolts, diametrically opposite, which extend across a coupled joint from lugs welded to the pipe on either side of the joint. Joint harnesses are particularly effective on unanchored bends subject to pulsating pressures of sharp intensity. 

AWWA Manual M11 compliant ring type restraint is also available upon request. 

American Iron and Steel (AIS) compliant and Buy America/Buy American compliant products available by request.
