NuFish Zipp Internal PTFE Bushes

Precision machined Polytetraflouroethelyne is used to produce these perfectly formed PTFE bushes, they have been designed to have the thinnest of wall thicknesses to give more internal clearance inside the pole for the elastic to run and a crisp neat shoulder for seamless fitting.
