These cushion loop clamps — also commonly called P-clamps or cushion clamps — are suited for HVAC, plumbing, automotive, aerospace, and industrial pneumatic and hydraulic systems. The EPDM cushion firmly grips lines to reduce noise from rattling, humming, and clanking while protecting surrounding structures from vibration-related fatigue.
