Customized PEEK / PTFE Plastic Backup Rings Washer Gasket
Custom Plastic Washer Rings and Gaskets: PEEK and PTFE Material Selection
Material options for drawing-specific washers:
Virgin PTFE: specify sealing or bearing duty, contact load, temperature and dimensional stability requirements before selecting the grade.
Filled PTFE: glass, graphite, carbon or bronze fillers are separate grades. Select filler type and proportion against mating surfaces, wear requirements, chemical exposure and compression under load.
| Virgin PTFE | 100% PTFE |
| Inorganic filler PTFE | Glass fiber, graphite, bronze, carbon fiber or MoS2; grade and filler content by specification |
| Organic filler PTFE | Polyimide, aromatic polyester or polyphenylene sulfide; formulation by approval |
For PEEK or PTFE washer rings, provide inner diameter, outer diameter, thickness and tolerances; identify the polymer grade, filler designation and required application documentation.

Rubber O rings:
1) Standard O-Rings
Sizes: AS568 dash sizes or drawing-specific metric dimensions; identify the required standard and tolerance.
Materials: NBR (Buna-N), silicone, FKM, HNBR or EPDM by specification. Food-contact requirements need compound-specific documentation.
Color: Black, Brown, or custom color.
2) Custom rubber o rings, X rings, or kinds of seals and washers&gaskets.
Custom parts are quoted against an approved drawing or sample with mating dimensions.
Specify shape, color and hardness requirements with the part drawing.

For a washer or gasket quotation, send ID, OD, thickness, quantity and polymer grade. State whether the part seals, spaces or supports sliding contact, then provide fluid composition, temperature, clamp load and surface requirements. PEEK and PTFE are separate polymers; verify grade-specific properties rather than using rubber Shore A hardness for these plastic parts.
