Spacefiller Brass slide grease

lubricant or grease specifically designed for brass instrument slides, such as trombones or other brass instruments with movable slides.

Brass slide grease is commonly used to reduce friction and ensure smooth movement of the instrument's slides. It helps prevent sticking or binding of the slide, which can hinder the player's ability to move the slide quickly and accurately.

Typically, brass slide grease is applied directly to the inner slide tubes or outer slide stockings, where the slide parts come into contact with each other. It helps create a thin, lubricating layer that allows the slide to move freely while maintaining a tight seal.
