Ryco O-Ring Fittings and Seals for Hydraulic Systems
A RYCO O-ring fitting uses an O-ring for sealing instead of a flared seat like a JIC fitting. Known as UNO (O-Ring Boss) fittings, they are engineered to deliver leak-free connections by compressing an O-ring within a tapered port. These high-performance hydraulic o-ring fittings are trusted across industries where durability and precision matter most.
Overview of Ryco O-Ring Hydraulic Fittings
- Sealing method: Uses an O-ring compressed into a tapered port, not a 37° flare.
- Thread standards: Typically 60°, conforming to ISO 11926 and SAE J1926.
- Orientation: Elbows and tees feature a back-up washer and lock nut to position fittings before tightening.
- Interchangeability: UNO fittings share thread forms with JIC but differ in sealing, making Ryco o-rings and seals essential for compatibility.
