oe2 Masthead

One time use unit with industry best lead times

OE2 is a capped disc and plug design using conventional rupture discs, either flat or domed. The unit plug is typically made from brass with a nickel disc although other materials are available on request. OE2 is designed to prevent over pressurisation in numerous applications.

Elfab’s fully automated production lines are capable of rapidly producing large volumes of capped rupture disc assemblies in a wide variety of sizes, designs and burst pressures, allowing us to manufacture this product range on some of the best lead times in the industry.

Available with various inlet and outlet thread combinations for ease of installation, the OE2 is a cost-effective solution for your overpressure requirements.

Low maintenance solution for a wide range of applications

OE2 assemblies can be used in a variety of industries and in many different application from aerospace to fire protection.

The advantage of OE2 rupture disc assemblies is the high operational performance and good leak tightness (10-4 cc/sec)* coupled with the zero maintenance design.

Elfab have offered high integrity, high performance OEM pressure relief solutions to its customers, for over 40 years. Elfab’s OE2 device is available in a range of standard sizes and thread configurations. Alternatively, unique custom engineered solutions can be manufactured in line with our customers’ particular design brief.
