Needle Packing Screw for M1 / M2 Product Description
PTFE needle packings are solvent-proof and will last much longer than rubber o-rings, avoiding the swelling and cracking that rubber suffers when subjected to solvents.
A PTFE needle packing does not mean you\'ll never need to replace the packing - it just means it will take a lot more wear than a rubber part.
