1. What are o-ring face seal fittings?

O-ring face seal fittings, also known as ORFS fittings, are a type of hydraulic tube fitting that uses an o-ring compressed between two flat metal faces to create a high-pressure seal. They are designed for construction, oil and gas, mining, and other heavy-duty applications.

2. How do o-ring face seal fittings work?

The male fitting has an o-ring groove in the flat face, while the female fitting has a flat face. When assembled, the o-ring is compressed between the two flat faces, creating a leak-tight seal that can handle extremely high pressures up to 6,000 PSI.

3. What are the advantages of o-ring face seal fittings?

O-ring face seal fittings provide excellent vibration resistance, reusability, and ease of assembly/disassembly for maintenance. They are leak-free, high-pressure rated, and eliminate leaks caused by variations in assembly procedures.

4. What industries use o-ring tube fittings?

Industries that commonly use o-ring face seal tube fittings include construction equipment, agricultural machinery, oil and gas, mining, industrial manufacturing, and transportation.

5. Can o-ring face seal fittings be disassembled?

Yes, a key advantage of o-ring face seal fittings is that they can be easily disassembled and reassembled in the field, allowing replacement of the o-ring or the entire fitting assembly.

6. How are o-ring face seal fittings connected?

The fittings connect tubing by silver brazing the fitting body to the tube end. The male and female threaded components are then assembled, compressing the o-ring face seal.

7. Are o-ring face seal fittings reusable?

Yes, o-ring face seal fittings are designed to be reusable. The o-ring can be replaced when it shows signs of wear or damage.

8. What standards cover o-ring face seal fittings?

The SAE J1453 standard defines requirements for o-ring face seal hydraulic tube fittings for off-road construction machinery.

9. Do I need special tools for o-ring face seal fittings?

While basic hand tools can be used, it is recommended to use proper torque wrenches and assembly lubricants/sealants to ensure proper make-up torque and prevent galling of threads.

10. Where can I buy o-ring face seal fittings and components?

Major hydraulic fitting manufacturers offer complete lines of o-ring face seal fittings, including fitting bodies, nuts, crosses, adapters, and replacement o-rings for a range of tube sizes.
