X-RING 132.72X5.33

JF4-5.3313272 is an x-ring and can be used in rod/piston applications. The material used on this x-ring is made of NBR 70 shore.

The dimensions has an inner diameter of 132.72 mm, an outer diameter of 143.38 mm and a height of 5.33 mm.

About the sealing profile JF4

X-rings are double-acting and very similar to o-rings, yet have some advantages in dynamic applications. Eg. they show no tendency to twist during use due to the construction of the profile.

About the material NBR

Nitrile is a widely used nitrile butadiene and acrylo nitrile polymer. The NBR formulas typically contains between 30% and 50% acrylonitrile (ACN). The NBR which has a working temperature between -40°C and +100°C show extremely high resistance under different working conditions such as mineral oils (H, H-L and H-LP type lubricating oils) and grease and mineral based fire resistance oils (HFB and HFC group oils), vegetable and organic oils, and aliphatic hydrocarbons (propane, butane, petrol). NBR is not recommended for aromatic hydrocarbons (benzene, trichloroethylene, HFD type fire resistance oils), glycol and ether contained break hydraulics.
