PTFE-Rubber Composite Gasket | PTFE Flat Washer | High-Precision Chemical-Resistant Seal

Product Description

This sealing component includes two variants (PTFE-rubber composite and pure PTFE flat washer) engineered for high-precision, harsh-environment sealing. The composite version combines a rigid PTFE outer layer—renowned for its chemical inertness, low friction, and temperature resistance (-200°C to 260°C)—with an elastic NBR/FKM rubber inner ring that provides superior compression and leak-proof sealing. The pure PTFE variant offers extreme chemical resistance for static sealing applications. Both types feature a precision-molded circular flat design, ensuring a perfect fit for standard fastener and flange assemblies. Ideal for hydraulic/pneumatic systems, chemical pipelines, and automotive fuel systems, this gasket resists corrosive fluids, high pressure, and wear, delivering long-term reliability in critical industrial and automotive applications.

TECHNICAL PARAMETERS

Category	Details
Product Name	PTFE-Rubber Composite Gasket
Part Number	271955476
Material	Composite: PTFE (white, low-friction layer) + NBR/FKM rubber (black, elastic sealing layer); Pure PTFE variant available
Color	White (PTFE) + Black (rubber) / Solid white (pure PTFE)
Core Functions	Dual-layer sealing, chemical resistance, low friction, leak prevention, vibration damping
Design Feature	Circular flat structure with embedded rubber O-ring (composite type); Solid PTFE flat washer (single type)
Application	Hydraulic systems, chemical processing equipment, automotive fuel systems, pneumatic valves, food/pharmaceutical machinery

Advantages

Dual-Layer Synergy (Composite Type): PTFE’s chemical resistance + rubber’s elastic sealing create a leak-proof barrier for both static and low-dynamic applications, outperforming single-material gaskets.

Extreme Chemical Inertness: PTFE resists acids, alkalis, solvents, and petroleum-based fluids, suitable for food, pharmaceutical, and chemical processing.

Wide Temperature Tolerance: Operates from -200°C to 260°C, adapting to cryogenic and high-heat environments without performance loss.

Low Friction & Wear Resistance: PTFE surface minimizes friction between mating parts, reducing wear and extending assembly lifespan.

Precision Fit: Molded to exact dimensions for seamless installation in standard flanges/fasteners, eliminating fitment gaps and leakage risks

Applications:

Seals hydraulic/pneumatic valve flanges and cylinder end caps, preventing fluid/gas leakage and maintaining pressure stability.
Provides chemical-resistant sealing in industrial pipelines and reactors, protecting against corrosive media in chemical processing.
Seals automotive fuel system components (e.g., fuel injectors, filters), resisting gasoline/diesel corrosion and ensuring leak-proof operation.
Acts as a low-friction washer in fastener assemblies, reducing torque loss and preventing galling between metal parts.
Delivers hygienic sealing in food/pharmaceutical machinery (PTFE variant), complying with FDA/EU food contact standards.
