PRODUCT DESCRIPTION

Garlock Gaskets - GYLON® Family - Styles 3545
BENEFITS:
  • Tighter seal
    • Higher compressible PTFE outer layers seal under low bolt load - suitable for many flat face and glass-lined flanges*
    • Compressible layers conform to surface irregularities, especially on warped, pitted or scratched flanges
    • Rigid PTFE core reduces cold flow and creep normally associated with conventional PTFE gaskets
  • Excellent chemical compatibility
    • Pure PTFE withstands a wide range of chemicals
  • Easy to cut and install
    • Soft PTFE can be cut easily from larger sheets, reducing inventory costs and expensive downtime
    • Rigid PTFE core facilitates installation, especially on large diameter flanges and hard-to-reach areas
  • GYLON° Style 3540
    • Pure microcellular PTFE
    • Similar to Style 3545, but without rigid core
    • Ideal for wavy, warped, pitted or scratched flanges and for many types of flat face* flanges
MEDIA:
  • Strong caustics, strong acids, hydrocarbons, chlorine and cryogenics and glass-lined equipment. Conforms to FDA regulations.

NOTES:
Dramatically reduced leakage of GYLON® 3540 and 3545.
Average of three tests, using 580 psig nitrogen with 4,640 psi gasket load according to DIN 3535 requirements. All samples 1/16" (1.6 mm) thick.
* For flat face flanges, a minimum compressive stress of 1,500 psi (10.3 N/mm2) is recommended on the contacted gasket area for 150 psig (1.0 N/mm2) liquid service. Consult with the flange manufacturer to confirm that adequate compressive stress is available.

NOTES:
1 Based on ANSI RF flanges at our preferred torque. When approaching maximum pressure, continuous operating temperature, minimum temperature or 50% of maximum PxT, consult Garlock Engineering.
2 For 3565, HP 3560 and HP 3561, 1/16" thickness only.
3 ASTM F37B Sealability
ASTM Fuel A (isooctane):
Gasket load = 500 psi (3.5 N/mm2), Int. pressure = 9.8 psig (0.7 bar)
Nitrogen:
Gasket load = 3,000 psi (20.7 N/mm2), Int. pressure = 30 psig (2 bar)
4 DIN 3535 Part 4 Gas Permeability, cc/min. (1/16" thick)
Nitrogen:
Gasket load = 4,640 psi (32 N/mm2), Int. pressure = 580 psig (40 bar)

This is a general guide and should not be the sole means of selecting or rejecting this material. ASTM test results in accordance with ASTM F-104; properties based on 1/32" (0.8mm) sheet thickness.
