SBR Hydraulic Slipper / Pump O Rings Seals 70 ± 5 Shore Hardness ROH SFDA
Sealing Applications
O-Rings seals are used in a variety of fields: they are either used as sealing elements or as energizing elements for hydraulic slipper seals and wipers. Thus, the O-Ring is basically used in every field of industry including aerospace, automotive or general engineering.
Our advantages
Today, the O-Ring is the most widely used seal because of its inexpensive production methods and its ease of use. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.
The perfect O-Ring for each purpose
Our O-Rings are both cost-effective and perform highly in almost every environment. No matter if you need metric or inch, standard or custom-made O-Rings – any size of O-Ring seals is available – including giant O-Rings using our Fleximold™ process. Our rubber O-Rings are made of EPDM, FKM, NBR, HNBR
