Buying Guide

Match material to application

Choose Viton (FKM) for fuel, chemical and high‑temperature resistance; select other elastomers for food‑grade or low‑temperature needs

Confirm correct cross‑section and ID

Measure both inner diameter and width (cross‑section) to ensure a proper static or dynamic seal and avoid extrusion or leakage

Check durometer (hardness)

75A durometer like the listed Viton parts is a common balance of flexibility and compression resistance for many industrial seals

Consider pack size and spares

Buying multi‑packs helps with maintenance—several options here offer packs that reduce repeat ordering for common sizes

Evaluate chemical and heat specs

Review compatibility charts for solvents, fuels and expected temperatures; Viton 75A parts provide broad chemical resistance and higher temperature tolerance
