New pull test and compression test for Storz couplings

A storz coupling is a quarter turn internal lug coupling

In some industry usage like agriculture and irrigation it can be casting made for general hose connection and pressure undertake. However if it is used in firefighting which is rather demanding, a forged artcraft is always requested to guarantee the safety and duration of the couplings.

SMEcoupling has a recent breakthrough to forge a series of aluminum-alloyed Storz couplings of great mechanical strength.

Endure up to 10 tons of weight!

The coupling deforms yet not broken sandwiched by 10 tons of pressure throughout the test for minutes.

Possible Materials: forged or casted aluminum, brass & st. steel

Connection type : delivery and suction hose tail, bent, inner and outer thread BSP, NSW, NPT

Engineering type possible with SMEcoupling : For sure yes.

Genuine forging strength.
