Helpful note for customers outside New Zealand
We are New Zealand’s major supplier of polyethylene vacuum tubing and spiral cut distribution tubing for composites applications. Our tubing is made from virgin polyethylene and is of excellent quality. It is resistant to collapse when bent, even at high ambient temperatures. It also recovers its shape well after being clamped off. Unfortunately, delivery of polyethylene tubing by airfreight is expensive because of its low packing density. While we are pleased to supply starter quantities of tubing at no charge with our machines, we recommend that our non-New Zealand customers look for local suppliers of vacuum tubing and spiral cut tubing. Sources of supply can be polyethylene extruders, hose and pipe distributors, compressed air equipment suppliers and irrigation equipment suppliers.
All modules and components incorporated in our equipment are available as separate items. Module possibilities include our manifold assemblies and the miniature resin trap and control module from the MICRO system (refer to RT2 information sheet). Examples of smaller components include our silenced vacuum regulation valve with vacuum override for quick vacuum release and all of our O-ring sealed tubing connections. Vacuum related accessory items include a vacuum probe for eliminating dry spots, multipart bag connectors and machined plastic infusion ports.
If sourcing vacuum tubing and spiral cut tubing in your local region we recommend asking for translucent tubing, as this allows resin movement to be observed. While cost is obviously important, we recommend avoiding very low cost tubing as this is often thin walled for pressure duty only, or made completely from weaker reground material. Low cost tubing can be prone to collapse under vacuum, particularly in hot climates. Unless known to be suitable for vacuum duty, always test both vacuum tubing and spiral cut tubing for suitability before committing to a quantity purchase.

Tubing cutter for clean cuts in polyethylene tubing up to 23 mm (0.9”) in diameter.
Disposable O-ring sealed valves
Low cost valves to suit 12.7 mm (1/2”) and 19 mm (3/4”) inside diameter tubing. O-ring sealed, but O-rings not suitable for long term exposure to solvents such as styrene. Normally limited to single uses when infusing.
Joiners, elbows and tees to suit our standard tubing.
