Choose the correct gasket and installation instruction for your reliable tri-clamp connection

Proper installation & certified gaskets for a reliable, safe system

Guide to selecting the right Tri-Clamp gaskets for optimal sealing performance.

Tri-Clamp gaskets play a critical role in ensuring leak-free, hygienic connections for pumps, filters, and fittings in the biopharmaceutical industry. Choosing the correct gasket for your process is essential to maintaining system integrity and preventing contamination.

To achieve a secure and reliable seal, it’s essential to select the best gasket material for the process, follow the installation instructions, check the fittings for irregularities, ensure correct alignment of the fittings, and choose the Tri-Clamp that aligns with the process and intended use.

Select the right gasket material for the right process

What type of gaskets

For many years, the standard Tri-Clamp seal (Type 1) was the only option available. However, when DIN and ISO adopted the Tri-Clamp standard alongside ASME, the flange type (Type 2) was introduced simultaneously as a more user-friendly and easier-to-install option.

Initially, this flange type was only available in DIN and ISO sizes, where it quickly became the new standard. Over time, it was also introduced in select ASME sizes, though the traditional Type 1 seal remains dominant in ASME applications.

Choose the right tri-clamp type

Use the right tri-clamp type to ensure a leak-free, GMP-compliant connection.

Single Pin Clamp (2 Segments):

The most common and cost-effective clamp for general applications.

Double Pin Clamp (2 Segments):

More flexible than the single pin, making installation easier in tight spaces. Both have similar pressure ratings and clearances.

Three-Segment Clamps:

Provide evenly distributed clamping pressure and slightly higher service pressure ratings than two-segment clamps.

Heavy-Duty Clamps:

A bolted, non-hinged design that withstands twice the pressure of hinged clamps, ideal for high-pressure or permanent applications.

Installation & Maintenance

Clamp jaws should never touch after tightening, as this indicates improper compression. Causes may include a damaged clamp, over-tightening, or incorrect sizing.

Regular inspections ensure clamps maintain proper torque, especially in high-pressure steam lines where thermal cycling affects gasket compression. Over time, gaskets degrade due to aging or vibration, potentially leading to leaks. Scheduled maintenance, including gasket replacement and vibration checks, ensures safe and reliable process connections.
