MORTAR HOSE COUPLINGS THREAD ADAPTERS HEAVY DUTY SWAGE FERRULE CLAMPING


Mortar couplings bear a striking resemblance to cam and groove type of couplings. Connection is made by evenly closing handles to seal two mating couplings without using tools. Therefore they are easy, fast and reliable to operate; plus mortar couplings are structurally reinforced.


Mortar couplings are widely used as the outlet quick-disconnect fitting in mixer and spraying mortar machines, CONCRETE TRANSPORTATION VEHICLES and plastering units. The Cam handles are designed and made of robust malleable iron and casting steels so that couplings can undertake the pressure over 25 bars and to maximum 50 at closure.


As dealing with abrasive mass granules as mortar and plaster, hard materials of casting carbon steel and malleable iron are commonly selected. In some cases plastic nylon (red) are required especially as the machine outlet coupling, fitted with strong stainless steel Cam handles and pull rings. The side figure as the coupling half with internal BSP-Parallel pipe thread of DN25 1" of "System 22" made of red nylon compound plus 25~30% acid resistant glass fiber by injection molding production.


Popular sizing 1~2 inch is commonly divided by its mating distance between lines of groove center and bottoms of adapters. They are referred to as SYSTEM 22 AND 23.5 which cannot be exchanged. An adapter of "System 22" has practically 22.0 mm high closing distance that must be connected with a 22 system coupling half of its nominal dimension. Same as to "System 23.5" female and male coupling halves with height of 23.5 mm. A groove line checker is made applicable to all cam and groove types. "System 22" and "23.5" can also be measured and verified when the curve lines perfectly match with each other.
