O-SEAL® Fittings
Features and Benefits:
- A comprehensive line of 3-Piece Fitting Assemblies with O-Ring Face Seal connections (ORFS) that resist over-torque and stay sealed during vibration for a variety of high-pressure applications.
- Bubble-tight, self-sealing separable connections are utilized that provide the same leak-proof performance as a heat-sealed system.
- Straight, elbow, cross, and tee fittings offer versatile solutions to cater to your unique requirements, whether you need to alter flow direction, link multiple pipes or create branches from a primary pipe.
- Flexible break-remake sealing connections allow for easy disconnect and reconnect when necessary and ensure a reliable seal even in dynamic environments.
- Seamless integration with reliable O-SEAL® valve end connections create a simple installation and operation.

O-SEAL® vs. Mark VIII®: Which Do You Need?
While both offer CPV’s leak-proof O-Ring Face Seal (ORFS) reliability, they serve different needs:
- Choose Mark VIII® if: You need a separable fitting for tubing systems (up to 2″) that allows for easy “slip-in/slip-out” maintenance without springing the line. Ideal for tight spaces and high-vibration environments.
- Choose O-SEAL® if: You need a versatile solution for both pipe and tube (up to 2.5″ pipe / 2″ tube) with the widest range of configurations and pressure ratings (up to 6,000 PSI).
Note: Mark VIII® and O-SEAL® components are not interchangeable.
Frequently Asked Questions
What are O-ring Face Seal (ORFS) fittings?
O-ring Face Seal (ORFS) fittings are high-pressure hydraulic and pneumatic connectors that use an elastomeric O-ring compressed between two flat metal faces to create a seal. This design offers superior leak protection compared to metal-to-metal tapered threads, especially in high-vibration environments.
CPV’s Solution: CPV pioneered this technology with the O-SEAL® System. Unlike standard ORFS fittings, CPV’s design allows for “slip-in, slip-out” accessibility, meaning you can remove a valve or fitting from the line without cutting pipe or springing the system, saving hours of maintenance time.
Are Mark VIII fittings suitable for high-vibration environments?
Yes, Mark VIII fittings are ideal for high-vibration environments. The O-ring absorbs shock and vibration that would typically loosen or crack traditional metal-to-metal fittings. This makes them a standard choice for critical naval, aerospace, and industrial applications where reliability is paramount.
CPV’s Solution: Mark VIII® fittings were specifically developed to bring the vibration resistance of the O-SEAL® system to smaller tube connections. They provide a hermetic seal that withstands the rigorous vibrations found in US Navy vessels and commercial shipping, ensuring zero leakage where it matters most.
How well do O-SEAL® Fittings stand up to vibration?
In the world of industrial gas and fluid systems CPV understands fittings must endure extreme torque, relentless vibrations and harsh environments. CPV O-SEAL® Fittings are equipped with a unique union O-Ring Face Seal (ORFS) design to excel in these conditions.
CPV’s precision-designed fittings resist over-torque and vibrations, ensuring an uninterrupted seal, while robust exterior plating guarantees durability and rust resistance. They redefine reliability in industrial applications.
Why is the fit of an O-Ring Face Seal (ORFS) fitting so important?
When considering the integration of ORFS fittings into a high-pressure system, it becomes crucial to select the right product. ORFS fittings find applications in a wide array of industries, including oil and gas, military, marine systems, agriculture, transportation and more, all of which deal with high-pressure gases and fluids.
High-pressure gases and hydraulic fluids necessitate precisely controlled environments for their movement and storage. Furthermore, some gases and liquids can be highly volatile. In such scenarios, the consequences of leaks can be not only damaging but also extremely hazardous. This underscores the paramount importance of the fit.
To ensure the utmost reliability, ORFS fittings must be meticulously designed to secure a custom tubing system. They require specialized and innovative design features to prevent leaks and to ensure the O-Ring seal remains secure and free from slipping or pinching under prolonged strain.
