Bolted double pin high pressure tri clamps are a significant upgrade from the standard wing-nut clamp, with the ability to withstand twice the pressure of comparable sized single or double hinged clamps. High pressure bolted tri clamps are available in stainless steel SS304, with sizes ranging from 3/4 inch up to 12 inches. Larger sizes are available by special order. Intended for Tri Clamp fitting connection, high pressure clamps are commonly used in situations where temperatures fluctuate and PTFE gaskets are installed.
Pure 3A recommends that all high pressure clamps be tightened to apply proper pressure and ensure a solid, leak free seal. However, over tightening a high pressure clamp may cause the gasket to fail from over-compression and place too much tension on the clamp threads.
