35650-6604 by Garlock | GYLON® | Style 3565 | 0.063in Thick | 60in x 60in

BENEFITS:
Tighter seal Soft, deformable exterior conforms to surface irregularities; ideal for worn, warped or pitted flanges Stable blue core improves cold flow resistance Low bolt load requirements ensure a tight seal on glass-lined or wavy flanges† Direct sintering of GYLON® layers prevents leak paths and adhesive contamination Easy to install Unitized construction avoids jacket fold over Rigid core facilitates installation of large gaskets Minimizes inventory Custom-cut gaskets from large sheets offer convenience while reducing costly inventory buildup Ideal replacement for slit, milled, formed shield and double jacketed envelope gaskets†
MEDIA:
Moderate concentrations of acids ENVELON® and caustics, hydrocarbons, solvents, cryogenics, and glasslined equipment. Conforms to FDA regulations.

NOTES:
* Consult Garlock Applications Engineering when using flanges in pressure classes above 300 lbs.
** Patents #4,961,891; #4,900,629
† When sealing uneven flanges, gasket must be four times thicker than maximum gap between flanges.

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.
