Quantity
The Gylon 3500 Gasket is a high-performance non-metallic sealing solution manufactured from silica-filled modified polytetrafluoroethylene (PTFE). This 10-inch, Class 150LB gasket conforms to ASME B16.5 and operates across a temperature range of -268°C to 260°C . Each complete set includes a G10 insulating sleeve and washers plus a full ZPS (zinc-plated steel) hardware set, providing comprehensive electrical isolation and anti-loosening protection for critical piping systems .
Material Composition and Performance
Gylon 3500 Gasket represents a significant advancement over conventional PTFE gaskets. The nano-silica particle reinforcement acts as a physical cross-linking agent, restricting molecular chain movement and substantially improving creep resistance . Unlike traditional PTFE which suffers from cold flow issues, the Gylon 3500 formulation minimizes creep relaxation—testing shows an 18% creep relaxation rate compared to 25-30% for conventional PTFE, with bolt torque retention improved by 35-45% .

Identifying Genuine Gylon 3500 Gasket from Counterfeits
Given the prevalence of counterfeit products in the Chinese market, here are reliable verification methods :
Given the prevalence of counterfeit products in the Chinese market, here are reliable verification methods :
Visual Inspection:
- Genuine products display an even tan-brown color consistent throughout—cut faces match surface color. Fakes are often surface-dyed with grey or white cores visible when cut
- Authentic gaskets bear raised embossed markings reading"GYLON 3500 -1/8 3.2 mm USA GARLOCK GASKETS"with sharp, burr-free lettering. Counterfeits typically have ink-printed markings that can be scraped off
- The edge should be knife-cut with a square profile and no flash—fakes show rounded edges or heavy burrs
- Genuine products display an even tan-brown color consistent throughout—cut faces match surface color. Fakes are often surface-dyed with grey or white cores visible when cut
- Authentic gaskets bear raised embossed markings reading"GYLON 3500 -1/8 3.2 mm USA GARLOCK GASKETS"with sharp, burr-free lettering. Counterfeits typically have ink-printed markings that can be scraped off
- The edge should be knife-cut with a square profile and no flash—fakes show rounded edges or heavy burrs
Physical Testing:
- Thumb-press the center: genuine material feels"hard-yet-tough"with ≥80% recovery within one second and no fingerprint residue. Counterfeits feel either too soft or brittle
- Fingernail scraping: authentic Gylon 3500 Gasket is solid sintered PTFE with no layered structure. Fakes often reveal a"blue skin + white core"separation

- Fingernail scraping: authentic Gylon 3500 Gasket is solid sintered PTFE with no layered structure. Fakes often reveal a"blue skin + white core"separation
Burn Test:
- Ignite a feathered edge for three seconds. Genuine material self-extinguishes instantly with no dripping and emits a faint candle-wax odor. Counterfeits continue burning, drip, and produce acrid rubber or asbestos smells

Accessory Verification:
- Genuine G10 sleeves are dark-green epoxy-glass laminate with visible glass weave on cut ends. Fakes are black nylon or paper-phenolic tubes
- Authentic ZPS washers are 3mm thick yellow-chromated zinc with chamfered edges; counterfeits are 2mm bright-white zinc without chamfer
