Parker VSTI3/4EDCF Hollow Hex Plug 3/4 in Mbspp Steel

Product Description

The PARKER VSTI3/4EDCF is a hollow hex plug designed to cap or close off hydraulic and instrumentation tube fitting ports in high-pressure industrial systems. Machined from steel, it features a 3/4 inch MBSPP (Male British Standard Pipe Parallel) thread connection and carries a maximum working pressure rating of 9137 psi. The hollow hex drive allows installation with a standard hex key or socket tool, making it well suited for tight-access port locations. This fitting conforms to DIN ISO 8434 standards and is installed by hydraulic technicians and industrial pipefitters maintaining fluid power and process systems.

The VSTI3/4EDCF is used to seal unused ports on hydraulic manifolds, valve blocks, cylinders, and related high-pressure fluid power components. It is appropriate for both industrial and mobile hydraulic applications where a reliable, compact port plug is required. The MBSPP thread type is common in European and internationally specified hydraulic equipment. The rated temperature range of -40 degrees F to 250 degrees F supports a wide range of operating environments including outdoor mobile equipment and climate-controlled industrial facilities.

Compatibility

Designed as an OEM-style replacement hollow hex plug for hydraulic systems and fluid power components using 3/4 inch MBSPP parallel pipe thread ports per DIN ISO 8434.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial pipefitter. Depressurize and isolate the hydraulic circuit completely before removing or installing any port plugs. Use the appropriate hex key or socket sized to the hollow hex drive and torque to the system manufacturer's specified value. Inspect the thread and seating surface for damage before installation to ensure a leak-free seal.
