Which is all done in full compliance with regulations and a focus on high quality, long term durability and reliability.

Nitrogen gas spring failure can be a life-threatening disaster in your facility. Learn how Special Springs can help you safeguard against failure with our OPAS safety features.

The Benefits of OPAS in Your Nitrogen Gas Springs

OPAS is designed with a combination of an exhaust channel intersecting the rupture plug. The body is made up of an over stroke marker, retaining ring bushing rod and body. Under correct operating conditions, the safety device is not activated. If pressure exceeds the maximum allowed values, the OPAS safety device is activated, releasing the gas pressure in a controlled mode.

This release avoids the rapid ejection of parts, and in turn greatly reduces the risk posed to the users due to pressure accidents.

Choosing the Right Safety Features for Your Nitrogen Gas Springs

OPAS will activate when pressure exceeds the maximum rating for the Special Springs product you are using. Engineered for safety and reliability, Special Springs’ nitrogen gas springs offer the peace of mind and safety features needed for your operations.
