Symmetrical couplings
Symmetrical couplings – general information
Symmetrical couplings feature a symmetrical design of locking heads (both parts of the coupling are exactly the same – no distinction between a coupler and an adapter) Therefore they can be quickly and easily connected – by pressing both parts against each other and turning. It is important to connect the halves with the lugs spaced at exactly the same distance. High, unrestricted flow rate, resistance to contamination and external damage are the key features of the symmetrical couplings.
The symmetrical couplings are intended for the applications transferring, loading and unloading water or other liquid substances as well as dry loose materials. Widely used in fire fighting, irrigation systems, drainage systems, chemical and food industry, marine industry, construction industry and agriculture, etc.
There are many standards of the symmetrical couplings:
