The SP-Medium Spill Plug is the versatile "workhorse" for hydraulic technicians and heavy equipment mechanics. Covering a range from 8mm to 26mm (5/16" to 1"), this plug is designed to stop spills from medium-duty hydraulic hoses, industrial pipes, and coolant lines during assembly or repair. The tapered design allows for a simple "Push and Twist" installation, creating a secure vacuum seal that holds fluid back even in tilted or inverted lines. These plugs are temperature rated from -25°C to +90°C, ensuring they remain flexible and effective in harsh shop environments or outdoor field repairs. Used for

 agriculture equipment, construction machinery, industrial hose replacement, and marine engine service.
