Description
Our 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.

FAQ
What are the pressure ratings for the Premium Heavy Duty High Pressure Tri-Clamp?
Pressure ratings vary by size and temperature. For example, the 1.5" clamp is rated to 1500 psi @70°F and 1200 psi @250°F , while the 12" clamp is rated to 150 psi @70°F and 100 psi @250°F . See the Technical Specifications table for the full chart.
What torque should I use when installing these clamps?
Apply 12–14 Nm (approximately 8.85–10 ft-lbf / 106–124 in-lbf ) to achieve a repeatable, leak-tight seal. Always verify gasket alignment and ferrule cleanliness before tightening.
Which gasket materials are compatible with the Premium Heavy Duty High Pressure Tri-Clamp – SS304 (Sizes 1.5"–12")?
Common options include EPDM, FKM (Viton®), PTFE, and silicone. Select materials based on chemical compatibility, temperature, and regulatory requirements of your process.
Do these clamps meet sanitary process requirements?
Yes. SS304 construction and smooth contact surfaces support sanitary service in food, beverage, biotech, and pharmaceutical applications when used with compatible hygienic ferrules and gaskets.
