Circular Cross-Section Seals Made of Rubber According to PN-60/M-86961

What is PN-60/M-86961 Standard for?

The PN-60/M-86961 standard specifies the dimensions of circular cross-section seals (specifically O-rings) for dynamic connections in hydraulic and pneumatic systems (e.g., pistons, slides).

O-Ring Seals – What Are They?

Power Rubber offers ISO standard O-ring seals made from various elastomers such as NBR, EPDM, VMQ, FKM, and SBR. These rubber seals are highly elastic and durable, providing a wide range of applications. O-rings can be used in both static (where components do not move relative to each other) and dynamic (where movement occurs between the sealing surface and the components) applications. The choice of material for the O-ring depends on the medium being sealed and the operating temperature.

PN-60/M-86961 Standard

This standard defines the dimensions and tolerances for dynamic connections using O-rings with a circular cross-section. O-rings can be used in both static and dynamic applications. For static applications, the proper groove design and appropriate dimensions must be used to ensure a proper seal.

Example of Dimensions:

Example marking: 18.3 x 3 PN-60/M-86961, where:

• Inner diameter D = 18.3 mm

• Cross-section diameter d = 3 mm
