Metal O Ring for Internal & External Pressure:

Non-vented rings (OI & OE) are designed for lower pressure ranges. The perfectly closed O Ring design avoids ingress of the media into the seal. Moderate load, moderate pressure capability.

Internally (OVI) or externally (OVE) vented O Rings are designed for higher pressure. Besides the own seating load the seal is also energised by the system pressure.

Spring-energised metal O Ring for Internal pressure (OSI) and (OSE) for external pressure are designed for extreme low leakage at moderate pressures.

Gas filled metal O Ring for high temperature and moderate pressure applications. OGI for internal pressure and OGE for external pressure.


Metal seals are used in a wide variety of applications in aerospace. Specially the turbine engine section. Since the temperature in engine crosses the limits of elastomeric seals the only optimum solution is metal seals. For high temperature applications exotic materials like hastealloy, Haynes, Inconel and Eligiloy can be used.

In oil and gas applications metal seals are highly preferred. In applications like deep sea where the pressures are extreme and the environment is corrosive special seals are made. At times they are gold plated for excellent performance. In power generation these seals are used to seal various parts of turbine section.

Metal seals are used in a wide variety of areas in military and defense field. C-seals are used in the night vision systems which is a crucial part of today’s defense technology. Also metal seals play an important part in space application. PTFE coated c-seals and spring energized c-seals are used in cryogenic applications.

We manufacture metal o-ring seals used in sealing the leakage path between nozzle and manifold of Hot Runner systems. The seal (SS321 material) is hollow with a small vent hole on the ID. Due to its hollow structure the polymer enters in through the vent hole and provides internal resilience. This internal resilience keeps the seal inflated which prevents the leak.

As we are aware that Nuclear energy is the best source to produce energy w.r.t. the cost involved and its return on investment. With the ever increasing no. of nuclear installations and the risk of radiation it is important to seal the vessels at its highest limit. In achieving the goal of optimum sealing metal seals like, c-rings and spring energized c-ring seals play a very crucial role. To achieve the desirable leak tightness for extended period of time spring energized c- seals with Nimonic 90 spring and 2 layers of jackets, viz – Inconel and Aluminum are used. Metal seals are also used in the nuclear waste containment. Seals with various shapes, like race track, oval, square are manufactured for special applications.
