Rubber Seals

Standard O-rings are ideal for a wide variety of applications. Unfortunately they cannot solve every design problem. For this reason NewDealSeals developed several custom rubber seals which do not have the standard O-ring cross-section. The main advantage to make use of other cross-sections is the possibility to use this in existing grooves without the need to redesign.

On this page the most common custom rubber seals are briefly described.

Molded Rubber Parts

Molded Rubber Parts provide perfect custom solutions for the most advanced and specific sealing problems.

Molded Rubber Parts
Brown FKM Oil Seals

Oil Seals

Oil seals, radial shaft seals or Simmerrings® have been designed for sealing shafts and spindles.

Oil Seals
Brown rubber V-rings


V-rings are axial seals for shafts and bearings. V-rings seal axially against a counter face.



X-rings, or Quad rings®, are an alternative for O-rings. X-rings have four lips and therefore they have at least four sealing surfaces.

Blue FKM D-ring


D-rings are an alternative for O-rings. A D-ring has the same sealing characteristics as an O-ring, but the D-ring’s flat base ensures better stability in the groove.

Red silicone hollow O-ring

Hollow O-Rings

Hollow O-rings are an alternative to standard O-rings, when low closing force is required.

Hollow O-Rings
FEP Encapsulated O-ring

FEP Encapsulated O-Rings

Encapsulated O-rings consist of a elastomeric core with an fluor-plastic-encapsulation.

FEP, PFA O-Rings
Black Square O-ring

Square Rings

Square O-Rings, or Kantseals®, are an alternative for O-rings in axial static applications. Square rings have high sealing capacity and shape stability.
