PTFE Welding for Large Diameter Gaskets
Large diameter PTFE gaskets are often required in demanding equipment such as chemical reactors, food and beverage vessels, and heat exchangers. When gasket diameters exceed 1,524 mm / 60 in., traditional fabrication methods can introduce challenges that affect installation, sealing reliability, and long-term performance.
Many fabricators rely on dovetail-style segmented gaskets, joining multiple pieces together to create the finished gasket. These joints are sometimes wrapped with additional material or covered with form-in-place sealants to manage potential leak paths. While common, this approach can make the gasket harder to install and may increase the risk of leakage.
Durlon PTFE welding is designed to solve these challenges.
Using precision-cut PTFE segments produced on a digital flatbed cutting machine, Durlon bonds gasket sections together through a proprietary welding procedure. The process creates a large diameter Ring Type or Full Face gasket without relying on traditional dovetail joints, helping customers achieve a more dependable seal in critical service applications.
Built for Better Sealing Outcomes
For customers, the value of PTFE welding is simple: fewer installation concerns, reduced leak-path risk, and greater confidence that the gasket will perform as expected.
Durlon welded PTFE gaskets are especially useful when applications require:
• Large diameter PTFE gaskets over 60 in. / 1,524 mm
• Improved sealing reliability compared with traditional dovetail designs
• Easier installation of segmented PTFE gaskets
• Custom Ring Type or Full Face gasket configurations
• Wide gasket cross-sections up to 229 mm / 9 in.
• PTFE sealing solutions for chemical processing, food and beverage, and heat exchanger equipment
A Process-Focused Approach to PTFE Gasket Fabrication
Durlon PTFE welding combines precision cutting, engineered bonding, and in-house equipment expertise to manufacture large diameter gaskets with improved consistency.
The process includes:
Digital segment cutting
PTFE segments are cut using a digital flatbed cutting machine for accurate geometry and repeatable fit.
Engineered segment alignment
Each segment is prepared and positioned to support a consistent welded joint.
Proprietary PTFE welding
Durlon uses a proprietary welding procedure and specialized equipment designed by in-house mechanical engineering experts.
Finished large diameter gasket production
The welded gasket is manufactured as a Ring Type or Full Face gasket, with cross-sections available up to 229 mm / 9 in.
