Product questions
What thread and coupling type does DINV19-F-12G have?
It is a size 19 (3/4-inch) female quick-release coupling with a 3/4-inch BSPP parallel female port and a poppet valve. BSPP is not the same thread form as NPTF; verify the port thread before ordering.
Is this 3/4-inch coupling interchangeable with ISO A or ISO 5675 plugs?
Do not assume interchangeability. Holmbury specifies ISO A interchange for the 1/2-inch size, and says its size 19 US and UK versions differ and neither meets ISO 5675 dimensional requirements. Confirm the mating profile and regional version before ordering.
What are the pressure and flow ratings for DINV19-F-12G?
Holmbury lists a maximum working pressure of 300 bar (4,350 psi) when coupled and a rated flow of 106 L/min (28 US gal/min) for size DINV19. Check the complete hydraulic circuit and mating components against the operating requirements.
Will DINV19-F-12G fit my hydraulic equipment?
Equipment-specific fitment has not been established. Provide the equipment make, model and serial number, together with the existing coupling details and mating profile, so the connection and regional version can be verified.
