Glacier Tanks double hinge pressure clamps are available in stainless steel SS304, with sizes ranging from 1½ inch up to 4 inches. Larger sizes are available by special order. Double hinge pressure clamps are an upgraded solution for most intended Tri Clamp fitting connections. They distribute pressure more evenly and can handle a higher pressure load than single hinge clamps. The wing nut style tightening screw allows for quick and easy assembly without the need for extensive tools.
Glacier Tanks recommends that all standard double hinge pressure clamps be tightened by hand, with an additional maximum of two turns using a screw driver to apply proper pressure and ensure a solid, leak free seal. However, over tightening a pressure clamp may cause the gasket to fail from over-compression and place too much tension on the clamp threads.
