The Lamons-style WRI-LP is a spiral-wound type gasket with a conventional outer ring that can be PTFE coated and faced with either flexible graphite or expander PTFE. The gasket is designed for HF acid and other highly corrosive applications where there is a risk of crevice corrosion with a standard spiral wound gasket design. The Kammpro inner ring acts as a primary seal, eliminating fluid ingress and so preventing corrosion issues.

Lamons Style WRI-LP has a proven track record in HF applications and has been adopted by a number of major plants throughout the world including Exxon Mobil, UOP, Phillips Petroleum Company and Concoc Phillips.
