OAKENSTRONG Gasket Paper is our premium range paper which has a cellulose fibre base, impregnated with a glue-glycerine composition and meets the needs for a high quality, general gasketing material.

Oakenstrong is recommended for low heat applications where high oil and fuel resistance is required.

For thicknesses in the range of 0.15 mm to 0.80 mm the material is produced in a single pass. For thicknesses of 1.00 mm or greater, the paper is laminated (using a gelatine based glue/adhesive) to give the desired thickness. For example 1.00 mm is 2 x 0.50 mm, and 3.20 mm is 4 x 0.80 mm.

The lamination process takes place after the paper has been successfully impregnated; the paper is then trimmed to produce a finished width of 1000mm ± 5mm.

With a high glycerine contents, Oakenstrong provides an efficient gasket paper which is able to seal against petrol, oil and water in a variety of applications including carburettors, fuel pumps, front plate, oil pump, oil filter, side cover, timing cover, thermostat, water pump, gearbox input shaft, exit housing, top cover, gearbox to clutch, axle cover, axle shaft and many others.



  • Excellent oil and fuel resistance
  • Available in roll form over a range of thicknesses including: 0.15 mm, 0.25 mm, 0.40 mm, 0.50 mm, 0.80 mm, 1.00 mm, 1.20 mm, 1.60 mm, 2.00 mm, 2.40 mm, 3.20 mm, 4.80 mm, 6.40 mm.
