Custom Die Cut Felt Products Custom Gasket Mfg. has over forty years experience specializing in the manufacturing of precision die cut felt products. The most common felt products we supply include: felt gaskets, seals, washers, spacers, stripping, discs, anti-vibration and anti-squeak pads, bumpers, bushings, noise reduction linings, vibration mounts, shock dampeners, heat barriers, wipers, oil and grease retainers, dust and fuel oil filters, sound deadening, padding, insulation, plugs, light seals, lamp bases, lubrication wicking, dust shields and filters. Felt is matted wool which is subjected to moisture, heat and pressure. Wool is a versatile material, enabling it the unique ability to cushion, retain its resilience under pressure and seal out dust and lubricants. Felt is easy to die cut into any shape. In addition to our die cutting services, we are able to kiss-cut, score, fold and bend any grade of felt. Custom Gasket Mfg. felt gasket material is available in a wide range of thicknesses, colors, styles and densities. The standard thickness of felt ranges from .015" to 1.000", in increments of .031".

Custom Gasket Mfg. provides full production capabilities from prototype and short run quantities through large production runs. Custom Gasket Mfg. provides mildew resistant felt for outdoor or fluid applications. Felt is available with or without pressure sensitive adhesive (PSA) backing.

Die Cut Pressed Wool Industrial Felt Products

Die cut pressed felt productsCustom Gasket Mfg. fabricates all pressed felt products with high quality wool fiber. Pressed felt is made by using high quality wool fiber that is mechanically pressed into a specific density and thickness using heat, moisture and pressure. It is made with multiple layers of material and has excellent solvent resistance and stability in oil. Wool felt has excellent wicking properties and can absorb several times its weight in oil. It is often used as a lubrication wick and supplies small amounts of oil at a uniform rate. Pressed wool felt has excellent solvent resistance and oil stability.

Pressed wool felt is identified by the S.A.E. standards F-1 through F-55. Custom Gasket's variety of S.A.E. felt parts are manufactured to the required engineering specification. Lower number S.A.E. felts (F-1, F-2, etc) are more machine-able, better in vibration absorbing and have better abrasion resistance. S.A.E. wool felt is unaffected by sunlight and maintains its original form after prolonged periods of stress. All of our S.A.E. felts are ROHS compliant and can be certified to automotive specification FMS-302 (fire resistant). F-1 thru F-55 felt is available in various thicknesses, wool content, and densities. Wool or a blend of wool and synthetic fibers are mixed, carded and then steamed and felted.

S.A.E. Specification Pressed Wool Felt Products

The manufacturing of pressed wool felt is mandated by S.A.E. standards. To reference felt specifications, please view our S.A.E. Specification Descriptions Section below. These standards determine the wool content, density, and other physical and mechanical properties of the felt.

S.A.E. Specification Descriptions


  • S.A.E. F-1 (16R1) Color: White - Density: Hard

This is ideal for oil retention where the felt is not being compressed.  Also suitable for feeding low viscosity or light oil and where unusual strength and hardness are required.  This grade is an excellent material for wiping sheet metal and tube cleaning applications.  It also has a high resistance to abrasion which makes it ideal for polishing and finishing hard surfaces.  Typical uses include washers, bushings, wicks, door bumpers, polishing blocks, and parts in which wear resistance to abrasion are required.

  • S.A.E. F-2 (16R2): Colors: Pink, Black, Brown - Density: High to Medium

This is a high-grade felt of slightly less density and durability than S.A.E. F-1.  It is recommended for vibration mountings and the same general purposes as F-1 but where a felt of slightly lower quality is adequate.

  • S.A.E. F-3 (16R3): Color: Grey - Density: High to Medium

This is a high-grade felt of slightly less density and durability than S.A.E. F-1.  It is recommended for precision uses such as: vibration mounts, precision lubrication wicking, oil seals, bumpers, gaskets, automobile, aircraft, and machinery components.

  • S.A.E. F-5 (12R1): Color: White - Density: High to Medium

This is a high-to-medium grade felt.  It is recommended for precision uses where resiliency and durability are important factors.  These felts are commonly used for grease retainers, lubrication wicks, grease seals, wipers, shock dampers, spacer strip seals, weather stripping, dust shields, and noise reduction linings.

  • S.A.E. F-6 (12R2) & S.A.E. F-7 (12R3): Color: Grey - Density: Medium

This felt is similar to S.A.E. F-5 and recommended for similar applications, but where slightly less durable material is permissible.  These felts are commonly used for grease retainers, anti-squeak strips, anti-vibration pads, gaskets, grommets, journal lubricators, shock pads, oil retention pads, vibration/noise dampeners, wicks and wipers, spacer strip seals, weather stripping, dust shields, and noise reduction linings.

  • S.A.E. F-10 (9R1): Color: White - Density: Medium to Low

This felt is similar to S.A.E. F-5 in quality, but recommended for uses where abrasion and wear are not important factors.  These felts are often used for grease and oil retention, fluid storage and delivery, dust shields operating under less severe conditions, as well as for plug filters for gas and air.

  • S.A.E. F-11 (9R2) & S.A.E. F-12 (9R3): Color: Grey - Density: Medium to Low

This felt is recommended for grease and oil retention where the felt is confined and compressed in assembly.  It is also recommended for dust shields under less severe operating conditions where F-5, F-6 & F-7 are not required.

  • S.A.E. F-13 (9R4) & S.A.E. F-15 (9R5): Color: Grey - Density: Low

These are low density felts with a wide range of uses where resistance to abrasion, durability, and wear are not important factors.  Typical uses include: spacing strips, sound deadening, chassis strips, spacers, dust shields, pedal pads, dash liners, fuel oil filters, anti-rattle applications and grease and oil retention.

  • S.A.E. F-26 (8R5) Color: Grey - Density: Low

This felt is suitable for packing and padding when held in place between other materials.  This grade should not be used for mechanical purposes.  It is used for insulating seals, packings, gaskets and bushings.

  • S.A.E. F-50 (16R1X) Color: White - Density: High Grade

This is a high-grade, high-density felt similar to S.A.E. F-1.  The difference is that it is produced in thicknesses below 1/8".  This felt is recommended for mechanical applications where an accurate, thin, smooth, high-grade felt is required.  Typical uses include ball and roller bearing oil-retaining washers and small, dust-excluding washers.

  • S.A.E. F-51 (16R3X) Color: Grey - Density: High

This is a high-grade, high-density felt similar to S.A.E. F-3, but produced in thicknesses below 1/8". It is recommended for the same general uses as F-50, but in installations where tolerances and length of life are not as important.  It is typically found in thin cut parts such as gaskets, spacers and liners.

  • S.A.E. F-55 (12R3X) Color: Black - Density: Medium to Low

This is a medium-to-low density felt similar to S.A.E. F-7, but made in thicknesses below 1/8".  This felt is recommended for uses where thin felt is needed and high durability is not required, such as anti-squeak strips, anti-rattle strips, washers, and rectangles.
