Parker VSTI11/4EDCF Hollow Hex Plug 1-1/4 in Mbspp Steel

Product Description

The PARKER VSTI11/4EDCF is a hollow hex plug designed for industrial pipe and hydraulic fitting applications. It features a 1-1/4 inch male MBSPP thread and is manufactured from steel for reliable performance under demanding conditions. This plug is rated for a maximum working pressure of 9137 psi and a pressure rating of 4500 psi, with an operating temperature range of -40 degrees F to 250 degrees F. Manufactured to DIN ISO 8434 standards, it is installed by hydraulic technicians and industrial maintenance professionals wherever a threaded port closure or system blanking solution is required.

This hollow hex plug is suited for use in industrial hydraulic systems, fluid power circuits, and high-pressure pipe assemblies. It is commonly used to plug unused ports on hydraulic manifolds, cylinders, valve blocks, and related components in both stationary and mobile industrial equipment. Its MBSPP connection type makes it compatible with metric British Standard Parallel Pipe thread ports, a common standard in European-specification and internationally sourced hydraulic equipment.
