Wool Felt Gasket Material
Pressed wool felt is a dense, absorbent sheet cut into wipers, wicks, dust seals, polishing pads and vibration pads. The grade is called out under SAE J314. Felt soaks up water, so felt parts are cut dry by the sheet maker or a cutting partner rather than on our waterjet, and quoted from the same drawing.

What felt is used for
Felt is not a pressure gasket. It is the sheet for oil wicks and wipers on shafts and ways, dust and grease seals on bearings and covers, polishing and buffing pads, and pads that damp vibration or protect a finish.
SAE J314 sets the properties, thickness, width, mass and other requirements for each felt grade, so the grade on the print is the specification [S1]. Oils are fine; water and steam swell and weaken it. For a weather or dust seal that must shed water, use closed-cell sponge.
Why felt is cut dry
The waterjet soaks felt, and a wet felt part takes days to dry and may shrink or distort, so felt parts are cut dry by the sheet maker or a cutting partner and quoted from the same DXF or drawing. Send the grade, the thickness and the quantity; if no drawing exists, send a photo of the part beside a ruler, or the sample, and a Conquest representative tells you what is needed to quote it.

How we cut it
Felt, mica and tanged (metal-inserted) flexible graphite are the sheets on this index that do not go on our waterjet (homogeneous graphite does): the jet wets felt, and felt holds the water. Felt parts are cut dry on a knife or die by the sheet maker or a cutting partner, and quoted from a DXF, DWG or PDF like a waterjet gasket. Name the SAE J314 grade, the thickness and the quantity, and say whether an adhesive backing is wanted; adhesive-backed felt is cut with the liner on.
Where Wool Felt is used, and the usual alternatives
The print or the sheet datasheet governs; these are the sheets usually specified instead:
- Closed-cell sponge: when the part must seal against water or dust rather than wipe or wick.
- PORON® foam: when a thin cushion with low compression set is wanted.
- Cork-rubber: when the cover gasket must hold oil at low bolt load.
- Cellulose fiber: when a thin paper gasket in oil is enough.

Frequently asked
What do the SAE felt grades mean?
SAE J314 gives the trade designations of the commonly used felt grades, with specifications and tolerances for thickness, mass, wool content, chemical and physical requirements, color and width. Name the grade on the print.
Why is felt not waterjet-cut?
Felt absorbs water and takes days to dry. Felt parts are cut dry on a knife or die by the sheet maker or a cutting partner and quoted from the same drawing.
Can felt come with adhesive?
Yes. Adhesive-backed felt is cut with the liner on so the pad peels and places.
