Exceptional heat resistance, extremely resistant to ozone

Product: D-ring

D-rings are alternative rings for O-rings and have the same sealing characteristics as an O-ring. Different from an O-ring, a D-ring has a flat surface that ensures better stability. A D-ring can fit in grooves that are for O-rings and fills in the gap when squeezed. Our selection of D-rings comply with highly recognized DIN 11851 standard from Deutsches Institut für Normung (DIN).

Material: VMQ

VMQ is fully resistant to ozone and has good electrical insulation properties. The good thermal properties of silicone rubber allow VMQ to be used in applications that must tolerate both high and low temperatures. Silicone rubber can be used over a wide temperature range, from -60 to +200ºC.
