O-Ring,BUNA,CSL 842/843

This O-ring is made from Buna-N, which is also called Nitrile rubber . This is a round rubber ring made specifically for Solberg CSL series filter housings . It fits the CSL-842, CSL-843, WL-842, and WL-843 models perfectly . When you close the filter housing, this ring squishes between the lid and the base. That squish creates an airtight seal. No dirty air gets in. No pressure gets lost.

1. It loves oil.
Buna-N has excellent resistance to petroleum-based oils, fuels, grease, and hydraulic fluids . If your system handles these materials, Buna-N is a great choice.

2. It is tough.
This material has good tear resistance and holds up well to wear . It does not crack or fall apart easily.

3. It saves you money.
Buna-N costs less than Viton or silicone O-rings . You get a quality seal without spending too much.
