Strong Nylon PA 6, yellow threaded sealing plugs with drain head design are designed to protect unified/straight threaded ports and fittings according to DIN 3852-1 Metric, ISO 6149-1 BSP, SAE J 1926 UN/UNF. The plug is well engineered with five complete threads to provide a tight fit. The "sealing lip" enables each individual plug to provide a secure seal to a specific torque for each size. The plugs can be fitted and removed with a screwdriver, socket wrench, power tool or by hand. The plugs come in nylon (PA 6), low density polyethylene of yellow or natural color. Nylon naturally provides high resistance against hydraulic fluids, acids, base alkalines and solvents.
