Excluding VAT
The Genuine Koshin Coupling (Part No. 0110422) is an OEM high-pressure discharge coupling component engineered for Koshin 2-inch multi-outlet high-pressure gas engine pumps, including the SERV-50Z, SERM-50V, SERH-50V, and SERH-50Z series.
Precision die-cast from ADC Aluminum Alloy with standard 1-inch BSP (25 mm) threading, this coupling functions as the main structural retainer ring within the 0118009 Sealing Coupling Assembly. It is used across all Koshin high-pressure pump models to cap off and tightly seal any unused secondary discharge outlets, allowing maximum pressure to be directed through the primary discharge line.
