Gasket Paper

Gasket paper is a traditional, low-cost sealing material made from compressed cellulose or vegetable fibres. We stock gasket paper in sheet and roll form for low-pressure, low-temperature sealing in automotive, agricultural, and general maintenance applications where cost matters more than chemical resistance.

Material TypeCompressed cellulose / vegetable fibre
Temperature RangeUntreated cellulose -30 °C to +100 °C continuous; oiled grades (Flexoid-class) and vegetable fibre board to +120 °C continuous (dry service only)
Maximum PressureUp to 10 bar at ambient (oiled grades, ≤1.6 mm thickness, bolt-load dependent); de-rates with temperature — typically ≤5 bar at sustained 80 °C+. Low-pressure service only
Density0.8–1.2 g/cm³
Compressibility (ASTM F36)15–35% at 35 MPa
Recovery (ASTM F36)10–25% — poor recovery is the engineering reason cellulose paper gaskets are single-use
Tensile Strength (ASTM F152)5–15 MPa (grade dependent)
Water AbsorptionHigh (untreated); moderate (oiled/treated grades)
Oil ResistanceMineral-oil impregnation suppresses fibre swelling and improves handling — this is swell suppression rather than chemical resistance. For sustained oil service, specify NBR-bound CNAF or PTFE
Thickness Range0.2 mm to 3.2 mm
ColourTan, brown, or grey (grade dependent)

Physical Characteristics

Density

0.8–1.2 g/cm³

Tensile Strength

5–15 MPa (grade dependent)

Compressibility

15–35% at 35 MPa (ASTM F36)

Recovery

10–25% (ASTM F36) — poor recovery enforces single-use disposability

Chemical Resistance

Resistant To

  • Mineral oils and greases (oiled grades)
  • Petroleum fuels at ambient temperature (oiled grades)
  • Air and non-condensing gases
  • Dilute coolant and antifreeze mixtures

Limited Resistance

  • Water and aqueous solutions (swells over time; use treated grades)
  • Dilute acids (short-term exposure only)
  • Light solvents (may soften oiled binder)

Not Recommended

  • Steam or hot water (cellulose degrades rapidly above 100 °C in wet conditions)
  • Strong acids or alkalis, which break down the fibre structure
  • Ketones and aromatic solvents (these dissolve the binder)
  • Any application requiring long-term chemical containment; use CNAF or PTFE instead

Environmental Ratings

Flame Rating

Combustible. Not suited to fire-rated or high-temperature applications.

Standards & Certifications

Standards Compliance

ASTM F104 (non-metallic gasket material classification)

Common Applications

  • Automotive sump and side-cover gaskets
  • Tractor and agricultural equipment gaskets
  • Small engine covers and gearbox gaskets
  • Water pump and thermostat housing gaskets (dry side only)
  • Template material for marking out gasket patterns
  • General maintenance and workshop gaskets
  • Low-pressure ductwork and enclosure seals

Not Recommended For

  • Not suitable for steam, hot water, or sustained wet service. Cellulose absorbs moisture and degrades.
  • Low maximum temperature (120 °C); for higher temperatures use compressed fibre sheet or graphite
  • Low pressure rating, so not suited to pressure vessels or high-pressure flanges
  • Poor chemical resistance compared to CNAF, PTFE, or elastomer gaskets — suited to mild media only
  • Combustible. Do not use near ignition sources or in fire-rated assemblies.
  • Single-use gasket. Does not survive disassembly. Replace at every service interval.

Available Grades

Untreated Gasket Paper

Basic cellulose gasket paper for dry, low-pressure sealing. Our lowest-cost option for workshop gaskets and templates. Not oil-resistant.

Oiled Gasket Paper

Cellulose paper impregnated with mineral oil for improved oil resistance and handling strength. Our standard recommendation for automotive sump and cover gaskets.

Vegetable Fibre Board

Thicker, denser gasket board made from compressed vegetable fibres. Used where greater rigidity and higher bolt load resistance are needed, typically at 1.5–3.2 mm thick.
