Use and setup
This sealing component is intended for the airsoft assembly identified in its name. A correctly matched seal helps maintain the interface between the parts it joins, but dimensions and shape need to be checked carefully when replacing a worn or damaged item.
Compare the stated size and platform reference with the original seal. Rings that look nearly identical can differ enough to affect seating, compression or movement. Check the relevant parts diagram where available and make sure you are selecting the right seal for the intended location.
Care and checks
Remove the old component carefully and check the sealing surfaces for dirt or damage before fitting the replacement. Use only maintenance products suitable for the material and the host system. After reassembly, test for leaks or irregular movement as appropriate. Keep spare seals clean and protected from sharp edges so they remain suitable for future servicing.
