There is nothing like the sound of nickel tubes! Two 80 tubes can replace the 45 and 90 tubes on an axial conversion for a cleaner look, and softer more sweeping curve for better air flow. 

Used in tenor trombone wraps

 This is a tenor trombone 45 wrap tube 

Our newly designed tenor offset tube comes into the tenor valve squarely, and seats well in the valve port opening.  Excellent upgrade in this tube!

This tube is used in some rotary conversions. Inner span is  2.15"  Outer span is 3.35"  Tube OD is .600"  Tube ID is .560"
