Tri-Clamp Gaskets From USA Lab
FDA-Compliant Seals for Reliable Connections
Gaskets are the small parts that make a big difference. They provide the seal between tri-clamp fittings, keeping your system leak-free, sanitary, and compliant. At USA Lab, you'll find a complete selection of Buna-N and PTFE gaskets, with or without mesh inserts, so you can match your gasket choice to your exact process.
Designed for Hygienic, Leak-Free Systems
FDA-Compliant Materials
Available in Buna-N and PTFE to provide safe, reliable sealing for food, beverage, and laboratory applications.
Mesh Insert Options
Offered with fine mesh inserts ranging from 5 to 300 microns, allowing you to filter particulates directly at the gasket seal for cleaner flow.
Wide Size Range
Designed to fit a variety of setups, with tri-clamp connection sizes from 1.5" up to 12" for small- to large-scale systems.

Match the Right Gasket to Your Work
- Filtering out fine particulates? → Choose a Buna-N mesh gasket (5–300 micron options).
- Need a simple, FDA-compliant seal? → Use a standard Buna-N gasket.
- Working with harsh solvents? → Select a PTFE gasket for chemical resistance.
- Want both strength and flexibility? → Go with a PTFE envelope gasket with Viton filler.
Why Choose USA Lab Gaskets
- Selection of FDA-compliant Buna-N and PTFE options.
- Mesh gasket options with micron ratings for inline filtration.
- Wide size availability for standard tri-clamp connections.
- U.S.-based support and fast shipping.
Equipment That Works With Your Gaskets
Pair your gaskets with other USA Lab tri-clamp components to build a complete system:
- Tri-clamps to secure gaskets and fittings tightly in place
- Mixing vessels and tanks for building sealed processing setups
- Buchner funnels using mesh gaskets for trapping particulates
- Reactors to keep high-pressure or solvent systems leak-free
