Introduction of end face fully sealed rubber joints
End face fully sealed rubber expansion joint is rubber sealing face which is fully same with flange face, it have better sealing performance.
Except this point, it's same with common rubber expansion joint, it's still consist of nylon cord fabric, inner and outer rubber layer, flange is usually carbon steel galvanized, rubber is usually EPDM, of course, other material is also acceptable, such as stainless steel flange, NBR rubber, neoprene rubber etc.
Working temperature is -15℃ - +80℃(the special can reach -20℃ - +150℃) celsius degree and the normal working pressure is PN16.

Precautions for installing end face fully sealed rubber joints
1. Rubber joints should be installed according to the natural length of the product, and it is strictly forbidden to install outside the displacement limit.
2. The pipe must be supported by a fixed bracket or bracket, and the rubber joints at both ends must have a fixed bracket. The closer the bracket and the rubber joint, the better.
3. The force of the pipeline fixing support must be greater than the axial force, and the joint shall not bear the weight and axial force of the pipeline itself.
4. Please install within the value range allowed by the product. Out-of-range displacement and deflection can cause the rubber joint to leak or fall off.
5. The bolts should be gradually tightened at the corners. Over-tightening can damage the sealing surface.
