These fittings are designed for gravity Sewers or Stormwater applications, but many can also be used in pressure applications.

(Contact Mill-Pro for detail on what pressures > 0.5 Bar can be applied to specific drainage fittings in our range.)

Mill-Pro offers a standard range of fabricated Polyethylene drainage fittings from 110mm to 2000mm from SN6 to SN100, however any PE fitting can be custom-made, typical standard fittings are; 

• S Trap with rodding eye for draining the base of manhole chambers (DSD standard design)
• Transition Fittings connecting PE to traditional materials such as; Reinforced Concrete Pipe (RCP), Vitrified Clay Pipe (VCP), PVC Pipe, PP Pipe, Ductile Iron (DI) pipe.
• Sliding Manhole Joints (SMJ) connecting PE to concrete manhole chambers
• Rigid Manhole Joints connecting PE to concrete manhole chambers
• Puddle flanges - available with an optional hydrophilic water stop seal 
• Fabricated segment bends for gravity use with radii up to R=10
• Junctions size on size and reducing Oblique 45º branch tee and a Swept Branch Tee 90º 
• Eccentric reducers for maintaining level invert between PE mains 
• Wye junctions 

Fittings are manufactured in accordance with EN 12201-3 / ISO 4427-3 and fully comply with EN 12666-1 using factory butt welding techniques to ISO 21307 making them suitable for pressure testing to 0.5 Bar. 

Mill-Pro does not use extrusion welding in the fabrication of any of its fittings.

Radius R = 1.5DN – to 10.0DN (Designed for gravity due to physical size – larger radius are not typically used in pressure applications).

NOTE:

Larger radius are sometimes called for when bends ≥ 45º are required such as R=7 x OD, R=10 x OD
