Felt and Textiles
Felt & Textile Washers
Advanced Seals & Gaskets offer an excellent in-house cutting service, using high-quality material and state of the art machinery, we can offer washers cut from a range of non-metallic materials including various types of textile and felt. Our felt washers are manufactured using samples, dimensions or drawings provided by our customers which would detail the Outer Diameter (OD), Internal Diameter (ID) and the thickness, and supplied with a plain or self-adhesive finish to one or both faces and in a choice of individually cut parts or kiss-cut in roll for quick and easy application. From a one-off sample to multi-thousand runs, we have a machine to quickly and accurately produce perfectly formed washers in a range of sizes, these include a number of presses and CNC machines.
What are Felt Washers?
A washer is a flattened ‘ring’ of material that is placed between two surfaces often to reduce friction and damage between moving components, prevent unsteadiness, to create a smooth, level surface for nuts/bolts to rest on (or allow for a better fit) and to create a seal. Our felt washers are generally produced using material made from either wool, polyester or a combination of both, these versatile material combinations have to cushion properties, remain resilient under pressure and create an excellent dust seal.
Why use Felt Washers?
Felt washers are used to fill gaps and irregularities between 2 surfaces and to provide a solution to unwanted rattles, noise, vibrations, to seal against dust and can also be used to cushion between moving parts to reduce friction and damage to components and equipment. Felt washers have a fibrous structure that can be used as a ‘wick’ to absorb and transmit fluids. They have excellent recovery, high energy absorption and a working temperature range of -40℃ to +100℃, typically found used as oil seals or filters in engines.
Our felt types are available in wool, polyester or a combination of both.
Woolen felt is produced using a combination of heat, moisture and compression, causing the wool to fuse without the need for any binders or binding agents to be assessed. Woolen felts are available in a range of hardnesses, a flame retardant grade and usually in black, white or grey colour options.
Synthetic felts are produced using man-made fibres, constructed by ‘needling’ or using chemical binders and heat. These felt do not perform as well compared to woollen felts when it comes to compressibility, elasticity, absorption and abrasion.
Benefits of Felt Washers
Depending on the type and grade of felt washer taken, the material will offer a whole host of properties and benefits, some of which include:
- High strength & resilience under pressure
- Excellent seal against air and dust under compression
- Excellent anti-vibration solution
- Thermal insulation properties
- Good acoustic properties
- Flame retardant properties (certain grades)
- Fluid wicking
