Thermo ORS, what am I actually getting here, is it a hose end or a fitting?

Answer by: Customer Support on Apr 22, 2025, 6:18 AM

You are getting an Aeroquip hydraulic fitting that uses an O-ring face seal (ORS) end connection. ORS is a common style in hydraulic systems when you want a leak-resistant connection under pressure, using a metal-to-metal face with an elastomer O-ring doing the sealing.
