This Mission adaptor coupling is designed with a stepped moulded sleeve that allows it to connect drainage pipes of different diameters together. Each end has a stainless steel clamping band used to create a strong seal between the pipe and the coupler.

One end of this drainage adaptor can be connected to a pipe with an outside diameter of between 345mm and 370mm, while the other end can be connected to a pipe with a reduced outside diameter of between 310mm and 335mm. Due to its robust design, this flexible drainage coupler has the ability to provide a reliable seal on any pipe material whether rough (e.g. concrete) or smooth (e.g. PVCu).

Product Features at a Glance:

• Made from EPDM rubber
• Quick and easy to install
• Stainless steel clamps ensure a tight seal
• New “locked-in-place” profile ensures end clamps remain securely in place
• Ideal for connecting:
  • pipes of different outside diameters and/or materials without the use of a bush
  • pipes to prefabricated structures e.g. manholes, inspection chambers, septic tanks
  • laterals to sewers or drains

Manufacturer’s Notice: The necessary compression of the rubber sleeve can only be guaranteed by a proper positioning of the stainless steel components.

Mission Flexible Drainage Fittings
Mission Rubber (UK) Ltd is part of the worldwide Mission Rubber group of companies who, over 50 years ago, invented the flexible rubber coupling for the sewerage, drainage and plumbing industries. Since then Mission has grown to become the world´s No 1 manufacturer of rubber flexible couplings with manufacturing plants in both America and Europe, and distributors worldwide.

Flexible rubber drainage fittings offer a perfect solution to joining pipes of various materials in drainage, sewerage and plumbing installations. They consist of a rubber body with stainless bands that enable them to compress down uniformly, onto different sizes and types of pipe, to form a reliable, airtight and watertight seal. It is a robust design that is aided, in some couplers, by a centre shear band which provides resistance against heavy earth loads and shear forces, helping to ensure pipe alignment with joint flexibility.

Flexible rubber fittings are ideal for joining plastic drainage pipes to other drainage materials such as clay, concrete, twinwall, stainless steel, cast iron and pitch fibre.

Key Features of Mission Fittings:

• Unique “Lock In Place” Rubber Profile
  • Made from EPDM rubber
  • Ensures clamps and shear band are properly positioned
  • Remain firmly in place during transit, stocking or installation on site
  • Internal stepped sealing lines achieve a better sealing effect
  • Additional EPDM sealing material can be compressed through sealing lines - giving special advantage for sewer pipes with rough surfaces e.g. concrete pipes
• TOX - TECHNOLOGY Clinching Process
  • No spot welding of clamps to the shear band- heat created during the welding process burns the stainless steel
  • Eliminates negative aspects associated with spot welding
  • Bond meets or exceeds all relevant tensile strength and shear requirements
  • Incorporated in the shear bands on all Mission couplings
