Parker VSTI11/2EDCF Hollow Hex Plug 1-1/2 in Mbspp Steel

Product Description

The PARKER VSTI11/2EDCF is a hollow hex plug designed for use in high-pressure hydraulic and industrial fluid systems. Fitted with a 1-1/2 inch male MBSPP thread, this plug provides a secure, leak-resistant port closure in steel manifolds, valve bodies, and hydraulic circuit components. Manufactured from steel and rated to a maximum working pressure of 9137 psi, it is built to handle demanding service conditions across a wide temperature range of -40 degrees F to 250 degrees F. Licensed plumbers, pipefitters, and hydraulic technicians install this fitting type during system assembly, maintenance, and circuit modification work.

This hollow hex plug is suited for industrial hydraulic systems, fluid power circuits, and high-pressure plumbing applications requiring MBSPP port closure. It conforms to DIN ISO 8434 standards, making it appropriate for both domestic and internationally specified hydraulic assemblies. Typical applications include plugging unused ports on hydraulic cylinders, manifolds, and control valves during commissioning or reconfiguration. The steel construction and MBSPP thread form make it compatible with metric British Standard Parallel Pipe port configurations commonly found in industrial and mobile hydraulic equipment.

Key Features

• Maximum working pressure of 9137 psi for high-pressure hydraulic service
• 1-1/2 inch male MBSPP thread for metric British Standard Parallel Pipe port fitment
• Steel construction provides durability in demanding fluid power environments
• Wide operating temperature range: -40 degrees F to 250 degrees F
• Conforms to DIN ISO 8434 standards for internationally specified assemblies
• Hollow hex drive allows installation with standard hex key or socket tooling

Compatibility

Designed as an OEM-style replacement hollow hex plug for hydraulic and industrial fluid power systems requiring a 1-1/2 inch male MBSPP port closure conforming to DIN ISO 8434.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic circuit completely before removing or installing any port plug. Use a properly sized hex key or socket to achieve a secure fit without overtightening, which can damage the port threads. Verify thread form and size compatibility before installation, as MBSPP threads are not interchangeable with NPT or BSP tapered thread forms.
