Filter Seal
Have you ever had to cold-start your equipment? If yes, then a Buna O-ring is an excellent choice for your hydraulic filter. Buna O-rings provide superior resistance to tear and abrasion during those cold-flow applications and they are the perfect ring when you decide to marry that cold-flow with petroleum products..

· General purpose sealing

· Petroleum oils and fluids

· Cold Water

· Silicone greases and oils
