Developed by British trumpet expert Will Spencer, it contains an additive called PTFE. PTFE is already used in products like non-stick cookware and dental floss, is one of the most slippery substances known to man. The difference it makes is unbelievable! This oil also contains a special anti-evaporation agent that makes it extremely long-lasting. Works great on both piston and rotary valves.

New packaging features a finer aperture to allow for more precise application and a locking top that can't become accidentally unscrewed.

50ml/1.7oz bottle.
