Liquid Tightness

Liquid-tightness

Standard access doors fitted with a polyethylene (PE) gasket offer a limited liquid-tightness (they are considered splash-tight). 

A better liquid-tightness can be achieved using access doors fitted with a rubber edge molding (SKK), assuming it has been cut and installed properly. It must be ensured that no joints or seams cross the opening and that the access door is installed according to our instructions.

This is why a new liquid-tight access door version has been developed. The new access doors are fitted with a special NBR gasket and NBR O-Rings.

Internal tests demonstrate that these access doors remain oil-tight when subject to a positive pressure of 3300 Pa (security factor 3). In less ideal conditions a slight leakage over the long term cannot be ruled out (please refer to the NBR characteristics: ZI-210).
