DOUBLE WALLED TUBING (PTFE)

For double wall tubing a PTFE tube is installed inside a 3/4” x 5/8” LDPE (Yellow or black) outer tube or for some smaller sizes we can offer a 1/2″ x .375 outer tube. The outer tube will provide mechanical protection and also secondary containment for the inner tubing and is available by the metre in the following sizes.

CSS use PTFE 62 which is a premium resin that has increased thermal stability, flexlife, stress-crack resistance and clarity.

All outer tube in either OD size is UV stabilised in both yellow or black.  Please specify outer tube colour and size when ordering.

Please note the longest length double walled tube with a continuous inner and outer is 100meters.

On certain sizes we can do a longer continuous inner with just an outer joint.  A surcharge applies for this service.
