Unthreaded Spacers

Nylon Unthreaded Spacers

These spacers have excellent wear and abrasion resistance. Exposure to moisture may cause them to expand.

Polyethylene Unthreaded Spacers

Almost nonabsorbent, these unthreaded LDPE and HDPE spacers won't swell when exposed to water.

Acetal Unthreaded Spacers

Naturally slippery and wear resistant, acetal spacers also offer some resistance to moisture.

Polypropylene Unthreaded Spacers

Polypropylene spacers have a hard surface and resist many chemicals and solvents.

PTFE Unthreaded Spacers

PTFE spacers have a slippery surface and surpass most plastic spacers when it comes to chemical resistance and performance in extreme temperatures.

PEEK Unthreaded Spacers

Use PEEK spacers as an alternative to metal spacers in high-temperature, high-stress applications. They resist chemicals, wear, and moisture.

Polycarbonate Unthreaded Spacers

Made of FDA-listed material, these clear spacers can be used in food and beverage applications.

Unthreaded Spacer Stock

Cut stock to the length you need.

Electrical-Insulating Unthreaded Spacers
