Custom made nbr FKM pipe rubber seal ring

A pipe rubber seal ring must match its receiving seat and the medium within the particular pipe joint. NBR and FKM or Viton-related options represent different formulations, not a universal combination of properties. The actual fluid and operating conditions should guide selection.

Check the ring's section and diameter against the joint geometry, including any groove or shoulder that locates it. The seal should reach its intended position without being stretched over a sharp edge or left unsupported across a gap. Any pressure requirement belongs to the evaluated complete connection.

Keep the ring and mating parts free from debris during assembly and inspect for twisting before closure. During servicing, compare the contact pattern with the intended seat. Swelling, cuts or permanent deformation can change the fit even if the ring still appears to occupy its groove. Replace using the defined material and dimensions rather than choosing a similar-looking ring whose behavior in the current pipe service has not been established.

Material options

NBR / FKM. Custom formulation and color for the intended contact conditions.

Hardness selection

Rubber: 30–90 Shore A. The seal should reach its intended position without being stretched over a sharp edge or left unsupported across a gap.

Custom dimensions

Check the ring's section and diameter against the joint geometry, including any groove or shoulder that locates it.

Fit & assembly

Keep the ring and mating parts free from debris during assembly and inspect for twisting before closure.

Use & inspection

Replace using the defined material and dimensions rather than choosing a similar-looking ring whose behavior in the current pipe service has not been established.
