5 Pcs Premium Density Brass Spit Corks

A set of 5 precision-cut natural cork pads engineered for dependable spit valve operation on brass wind instruments. Each pad is approximately 12 mm in diameter and 4 mm thick, made from sustainably harvested, tightly compressed cork. Total net weight: 15 g. The material exhibits balanced absorption — drawing in moisture without oversaturation or dimensional change — and resists microbial growth associated with prolonged saliva contact. Its firm yet slightly compressible nature provides secure seating in valve threads while allowing smooth actuation. Suitable for regular maintenance on trumpets, trombones and similar brass instruments where reliable valve sealing directly impacts playability and hygiene.
