Pressure Testing


Explosion Pressure Testing

Title Line

Independent explosion testing has been undertaken by Rocket Lab Ltd on BFM® fittings. The tests were also repeated with standard Seeflex material and silicon fastened with traditional hose-clamps for comparison.


Chemical Testing

Title Line

Chemical TestingSeeflex 040E, as with all urethanes will resist differing chemicals in different ways depending on a huge number of factors, from concentration levels to usage and temperature. The information and test results provided in the document should be used as an indication.


Vacuum Testing

Title Line

Vacuum TestinBFM® Global undertook testing to determine the time it would take for a BFM® fitting, under vacuum, to drop pressure from 500mm W.G to 400mm W.G, and compare this with a standard clamp-style connector.


Explosion Testing

Title Line

Independent testing of BFM®'s products prove how effective they are at containing explosion pressures.
