• [A quick solution to jack oil leaks and pressure loss] ``Oil is seeping from the floor jack'' ``Even if you pump it, it won't go all the way up''...The cause may be a deterioration of the oil filler plug (rubber stopper)! By replacing it with this repair rubber stopper, you can regain strong sealing and restore the jack's original lifting force.
• [*Important: Please check the size of the inlet hole before ordering] The size of this product is [approx. 1.40 x 1.40 x 1.10 cm]. Adopts a "flat head" type that does not protrude from the jack head. The diameter of the injection port varies depending on the manufacturer and tonnage (2t, 3t, etc.), so please be sure to measure the hole size (diameter) of your jack before ordering.
• [Highly durable and oil-resistant rubber that can withstand harsh environments] Uses a rubber material with excellent oil resistance, abrasion resistance, heat resistance, and cold resistance, which is designed for harsh environments that come into contact with engine oil and hydraulic oil. It is resistant to hardening and cracking (aging) even after long-term use, and firmly seals the pressure inside the hydraulic cylinder.
• [Easy maintenance, just push in, no tools required] Just pry out the deteriorated old rubber stopper with a flat head screwdriver, etc., and replace it by pushing in this product. It has a flexible design that is easy to handle and allows for smooth opening and closing when replenishing jack oil and performing air bleed operations.
• [Set of 5 pieces to have as a spare] Rubber stoppers are consumable items that easily get damaged during regular jack oil changes. This product is delivered in a generous set of 5 pieces, so it can be kept in a tool box by a maintenance shop that owns multiple jacks or as a spare (stock) part in case of an emergency.
