Description
Premium Heavy Duty High Pressure Tri-Clamp – SS304 (Sizes 1.5"–12") | USA Lab
Our USA Lab Premium Heavy Duty High-Pressure Tri-Clamps are built using a thicker, reinforced clamp body compared to our standard high-pressure tri-clamps. The increased metal thickness provides greater rigidity, improved sealing force, and enhanced durability under demanding pressure loads.
Standard high-pressure tri-clamps are still reliable and rated for elevated pressures, but the premium heavy-duty version offers an upgraded structural design for users who need maximum strength, longevity, and safety—especially in high-cycle or high-stress sanitary process applications.
Available in sizes 1.5" through 12", each clamp is designed for consistent sealing force and validated pressure ratings at 70°F and 250°F. Pair with compatible ferrules and gaskets to build code-compliant, serviceable process assemblies.
