Key Features
- Genuine OEM Construction — manufactured to Husqvarna's original thread and sealing specifications, delivering the same port integrity as the factory-installed component
- R 1/2 Thread Compatibility — machined to the standard R 1/2 taper thread profile for a secure, leak-free engagement without the need for adapter fittings
- Wide Equipment Compatibility — fits PP325E power packs, DM406 core drills, WS460, WS462, and WS463 wall saws, and the CS2512 wire saw, making it a versatile service part across multiple machine families
- Leak-Free Port Sealing — a correctly seated plug maintains system pressure and prevents fluid or air ingress at unused ports, protecting internal components from contamination
- Hydraulic System Safety — an unsealed or improperly threaded port can result in pressure loss or fluid leakage, creating a safety hazard on the jobsite; this OEM plug eliminates that risk
A VSTI plug is a solid, threaded port-sealing component used to close off hydraulic or pneumatic ports that are not in active use. On equipment such as power packs, wall saws, core drills, and wire saws, unused fluid or pressure ports must be securely capped to maintain system integrity and prevent contamination. When a plug is missing, damaged, or fitted with the wrong thread form, the machine may lose operating pressure, allow moisture or debris into the hydraulic circuit, or develop fluid leaks — all of which compromise both performance and operator safety. Replacing a worn or lost plug with the correct OEM part restores full port sealing and keeps the hydraulic system operating as intended.
