The Valken 42” SLP QD Air Rig is an air rig hose that every HPA owner needs with their tank parts. This is a low pressure wide bore air hose that is not only flexible and durable, but is also compatible with most self sealing QD connections used in airsoft HPA systems. They are enclosed in a dual layered nylon sheathing that will not affect flexibility, but will also help protect the hose from damage. These air rig hoses use 1/8 inch NPT threaded fittings, and have a maximum line pressure of 200 PSI. We recommend using our Valken Low Pressure Ultra Regulator with out SLP air rig hoses.
