Nickel ferrule for connecting our tenor rotary valve to our wrap tubes

 This is a tenor trombone 45 wrap 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"

Used in tenor trombone wraps

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!
