Double Handles: The grease gun with a pistol-shaped nozzle features a double handle for less effort when greasing. The handle has a fine, irregular texture to ensure friction with the palm of your hand and prevent accidental slippage. Leak-Proof Nipples: The Gun Grease nipples have tapered rubber seals to ensure that the seals do not leak oil and are very tight and durable. Can be used continuously. Reinforced jaws ensure stable long-term performance, as well as high-quality seals to prevent forward or backward leakage even at the highest pressures. Environmentally Friendly: The pump tip grease nipple does not require lubrication. No more grease, no more waste. Fits All Gun Oil: Pump tip grease fits all presses. Oil fittings with 1/8" NPT fittings. Compatible with all types of grease guns, including pneumatic, manual, and electric. Versatile: M6-M14 grease fittings fit all types of grease guns, including electric, pneumatic, and manual. Ideal for any machine that needs lubrication on construction sites, mines, farms, forests, maintenance facilities, or workshops.
