This particular PU tubing is designed for a reliable friction fit with 22 or 25 gauge swivels and couplers. The elasticity and thick wall minimizes the chance of accidental disconnection, kinking or puncture.
This tubing is used in our VAH and VAB™ tethers. The 22ga version is available with a white stripe to differentiate dual channel connections. For thin-walled PU catheter tubing see our intravascular PU tubing or, better yet, our finished catheters with rounded tips and suture collars.
