Integraflow supplies PTFE RJT seals (Teflon®) for hygienic union systems to BS 4825 Part 5. PTFE is a chemically inert, high-purity polymer offering exceptional resistance to aggressive chemicals, solvents, and high temperatures, making it the ideal choice for pharmaceutical, cosmetic, biotech, and ultra-clean food processing applications.

PTFE RJT gaskets offer:

• Total resistance to most chemicals and cleaning agents

• Non-stick, low-friction surface for excellent product release

• Operating temperature range of -200°C to +250°C

• Extremely low extractables, suitable for high-purity environments

PTFE seals are compatible with all RJT fittings and are frequently used where elastomer gaskets may degrade or absorb product. Available in imperial sizes from 1” to 4” OD, with full material traceability and rapid UK-wide dispatch from Integraflow.
