QUALITY CONTORL
Each AVLOK Coupling manufactured goes through stringent quality control, right from the procurement of raw material upto final stage.
PRECAUTION :
- Avoid connecting or disconnecting a coupling under pressure.
- Residual pressure in a coupling may make it difficult to connect. In such a case, do not strike the valve end to depressurize it.
- Improper selection of seal rubber may cause leakage.
- Dust or flaws in the seal may cause leakage.
- Improper selection or improper use of the products can cause personal injury and property damage.
