Description

Ordering Instructions:

  • Valve Piston Diameter
    • Enter the outside diameter of the valve piston to within 0.001" (0.025mm) in the text box above.
    • Size must be between 0.625" - 0.999" (15.87mm - 25.37mm). (For sizes 1" (25.4mm) and larger order barrel #2515LG).
    • If ordering multiple barrels separate sizes with slash marks or several spaces.
    • If two sizes are within 0.001" you can order just the smaller size and use it for both size pistons.
  • Measurement - click on the drop down arrow to select inches or millimeters.
  • Enter the total number of barrels in the quantity field and click add to cart.

Barrels are designed to be used with our #2510 Standard Valve Burnishing Tool and are precision cut to within 0.001" (0.025mm) so that at zero expansion they are the exact size of the piston diameter. It is important to note that barrels expand outward from their center and quickly lose their effectiveness as a burnisher if expanded more than 0.002" or 0.003". Several popular trumpet models however have piston sizes within 0.001" of one another (Yamaha 0.664" and Bach Stradivarius 0.665") and so ordering just one barrel cut to the smaller size 0.664" and using it for both models will provided excellent results. But trying to use one barrel for pistons with a wider diameter range will produce unsatisfactory results. Barrels are made from half hard brass and will work for many repairs.

If you are unsure or unable to accurately measure piston diameter contact us with the make and model of the instrument and we may have specification on size. Or you can send us the piston and we will measure it and return it with your order.

Allow 1-2 business days for barrels to be cut and ready for shipping.
