JIC 37° Flare Hydraulic Fittings Male Connector - O-ring Design
THMC-OR
JIC 37-degree Flare Hydraulic Fittings Male Adapter with O-ring.
For hydraulic systems exposed to high vibration or operating at low pressure, O-ring–sealed fittings are recommended to prevent leaks as they help reduce maintenance costs and minimize machine downtime. For water applications, the use of an O-ring design is strongly recommended.
This Male Connector is essentially a JIC 37-degree Flare Hydraulic Fittings Male Adapter, with the additional feature of an O-ring Face sealing.
Features
- Taper design to reach Leak-free and Crack resistance.
- With O-ring to improve vibration resistance.
- Heat resistance, impact resistance, corrosive resistance, and high temperature resistance.
