Product Description

Product Description

Washers are available in a variety of different materials to suit varying environmental and operating conditions. Although many industry professionals employ metallic washers, non-metallic washers, such as those made from nylon or PTFE, are becoming increasingly popular. In particular, polytetrafluoroethylene (PTFE)-also known by the brand name Teflon™-offers several advantages when used for the manufacture of washers.

Teflon or PTFE washers are flat discs with a centrally located hole. They have superior antifriction properties, as well as excellent chemical and corrosion resistance. These washers are ideal for low-temperature applications.

Washers can do way more than secure bolts, nuts, screws, and rivets. They can also insulate, seal, lock, serve as spacers, provide spring force, align parts, distribute loads, and even improve aesthetics. There are six primary types of washers: flat, shoulder, tab, lock, countersunk, and spring.

Main Properties & Application

• High melting point (620° F)
• Excellent insulating properties
• FDA approval for use in food and beverage or pharmaceutical applications
• Good chemical resistance
• Low friction for easy installation and product assembly
• Near-complete water resistance

APPLICATIONS

Our Teflon/PTFE washers find application in a wide range of industries-including automotive, HVAC, and plumbing-providing durable and reliable performance even when exposed to water, oil, chemicals, and high heat.
 

Teflon/PTFE Washer Vs Metal Washer

For a number of years, metal served as the default material for washers. However, the introduction of durable and reliable plastics, such as Teflon/PTFE, has led to the acceptance of plastics as a suitable alternative.

Teflon/PTFE offers several advantages over metals when used in the manufacture of washers. For example, it demonstrates:

• Water resistance, making it less likely to corrode
• Chemical resistance, making it suitable for equipment and systems that handle chemicals
• A low coefficient of friction, making it easier to work with and achieve a tight seal

Teflon/PTFE Washer Vs Nylon Washer

Compared to metal, nylon and Teflon/PTFE offer greater application versatility and durability when used in the manufacture of washers. While both are synthetic polymer materials with excellent mechanical strength and frictional resistance, they vary in regard to best use cases due to the differences in their manufacture and, consequently, their physical and chemical characteristics. For example:

• Teflon/PTFE is hydrophobic, meaning it resists mixing with water. Compared to nylon, it has a higher melting and better chemical resistance. These qualities make it suitable for equipment systems regularly exposed to moisture or requiring significant amounts of lubrication.
• Nylon is hydrophilic, meaning it readily mixes with water. Compared to Teflon/PTFE, it demonstrates better electrical conductivity.
