Common industries: Industrial equipment, lubrication systems, precision manufacturing, automotive, furniture manufacturing.
F-2 SAE Pressed Felt is a firm, dense wool felt at 30–40 Shore A, rated 9 on a firmness scale of 1–10, and available in pink — distinguishing it from the white F-1 and gray F-3 grades. It has a minimum of 95% wool content and is classified as ASTM D2475 34R1. It is intended for washers, bushings, wicks, door bumpers, polishing blocks, spacers, and abrasion-resistant parts, and is well suited for low viscosity oil absorption and retention.
The standard roll width of 60″ (1.52 m) and availability from 1/8″ to 1″ thickness make it a versatile format for fabricated felt components.
The material achieves 99% recovery after deflection, high vibration absorption (static and dynamic), 74% liquid absorption by volume, and a noise reduction coefficient of 0.50 at 1 in. Thermal condition is 0.36 btu/hr/sq ft/°F/in at 70°F. Split resistance (minimum) is 33 lb/2″ width.
Compliant with ASTM D2475 — Classification 34R1.
What differentiates F-2 SAE Pressed Felt from the F-1, F-3, F-5, and F-7 grades?
F-2 SAE Pressed Felt matches the F-1 grade in firmness (rated 9 on a scale of 1–10), tensile strength (500 psi min.), hardness (30–40 Shore A), and all physical properties, but is available in pink — making it the appropriate selection when a color other than white or gray is required. It is also supplied in a wider thickness range (1/8" to 1") with a standard roll width of 60" (1.52m), providing greater format flexibility than the F-1 grade.
Why is hardness important for felt selection in industrial applications?
Hardness in pressed felt governs how the material deforms under load, which directly affects its performance in sealing, wicking, polishing, and vibration absorption applications. A harder felt (Shore A 30–40 for F-2) resists permanent deformation under sustained load, maintains dimensional integrity in bushings and spacers, and provides consistent contact pressure over repeated use cycles. The F-2's 99% recovery after deflection confirms its elastic response to load cycling, supporting long-term performance in dynamic applications.
What is the temperature range for F-2 SAE Pressed Felt?
F-2 SAE Pressed Felt is rated for service from -80°F to +200°F (-62°C to +93°C), as listed on the TDS.
Is F-2 SAE Pressed Felt suitable for specification-controlled industrial environments?
Yes. F-2 SAE Pressed Felt is classified as ASTM D2475 34R1 and meets Federal Specification C-F-206G 16R1, as listed on the TDS.
How should F-2 SAE Pressed Felt be specified?
Specify grade (F-2 SAE Pressed Felt), thickness, compliance requirements (ASTM D2475 34R1 / C-F-206G 16R1), dimensional tolerances, and finished format.
