Mark VIII® Fittings
Features and Benefits:
- A complete line of 3-piece O-Ring Face Seal (ORFS) connection fittings that resist over-torque and stay sealed during vibration, ideal for high-pressure applications.
- Bubble-tight, self-sealing separable connections provide the same leak-proof performance as a heat-sealed system, without the need for heat.
- Straight, tee, cross and elbow fittings provide a variety of solutions for specific needs, such as changing the direction of flow, connecting multiple pipes or branching off from a main pipe.
- Low assembly torque reduces wear and tear, enhances sealing performance, simplifies installation, minimizes the risk of over-tightening and improves control.
- Crafted for seamless integration with Mark VIII® Shutoff and Regulating Valves, ensuring exceptional performance.
- Ease of maintenance with slip-in/slip-out accessibility and quick break-remake of connections reduces downtime and increases productivity.

CPV is a professional pipe fitting manufacturer that has a wide variety of both stainless steel and weld fittings.
Can Mark VIII® Fittings be heat sealed into a system?
Yes, Mark VIII® fittings can indeed be heat sealed into a system through various methods such as welding, orbital welding or brazing. Brazing offers a straightforward process that requires minimal training and basic tools.
CPV has conducted rigorous tests to highlight the exceptional durability of Mark VIII® Fittings. The brazing process allows us to successfully attach fittings onto a variety of materials, including brass, copper, steel and stainless-steel tubing. The brazing process was carried out using a handheld propane torch, showcasing the ease of installation.
In a significant observation, it’s crucial to mention that in every case, the tubing itself failed before our Mark VIII® Fittings did. The burst pressures recorded during these tests (the amount of pressure a tube or pipe can withstand before rupturing) were impressive, ranging from 9,000 to 16,000 psi. Notably, this substantially exceeded the rated pressure of 6,000 psi for Mark VIII® Fittings. This remarkable resilience underscores the reliability and robustness of these fittings, making them the trusted choice for applications prioritizing performance and safety.
Can Mark VIII® Fittings be customized?
Yes, by reducing tailpieces and reducing inserts, you have the flexibility to craft customized and unique solutions tailored to your specific needs.
