Poly Duct Fittings

We have developed and manufacture a new more advanced range of moulded polyethylene products, manufactured from linear Medium Density Polyethylene, a lighter material with better impact resistance than HDPE.

Standard Features of Polyethylene

• Non corrosive
• Flexible
• Inbuilt noise absorption
• Durable & Impact Resistant
• Light Weight (compared to steel)
• Low Maintenance
• Low friction coefficient (0.02)

Advanced Features of the Moulded Polyethylene (MDPE) Product Range

A more robust moulded cylinder which is:

• Seamless (products therefore have less welds)
• Inherently round (rather than fabricated & inherently flat)
• Double Rings (ensure that even under the highest pressure the bag will not blow off)
• UV Stable for outdoor storage
• Fire Retardants & Anti-Static additives available
• Compatible Joining System.

Range of Standard Fittings

Product Range includes:

• T-Pieces
• Y-Pieces
• Bends
• Branches
• 4 Way Sections

Other configurations can be manufactured on request including:

• Flange Adaptors
• Vent Bag Joiners
• Lobster Back Ends
• Reducers
• Oblique/Oval, Round-Oval Transitions
• Standard fittings available in diameter sizes 1065mm, 1200mm & 1400mm
• Other sizes can be manufactured to suit your specific requirements
• Standard fittings have the ‘double ring end’ to connect to Vent Bag with strapping
• Fittings with a ‘flange end’ can also be manufactured on request
• Directional Valves with a steel sleeve can be added to fittings to meet any requirement.
