Reducing Coupler PVC skt scj 110x90mm-P
Reducing Coupler PVC skt scj 110x90mm-P (Product Code: SLE/WDF/28) is a straight uPVC reducing socket used to join a 110 mm outside-diameter PVC pipe to a 90 mm one in a single in-line water-supply connection. Installers use it where a main narrows along its route or meets an existing 90 mm line; both female ends are solvent-cemented and the coupler is rated 10 bar at 20°C. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the 110 x 90mm PVC Reducing Coupler Used For?
Pipelines are often sized down as demand falls towards the far end of a network, and new work frequently has to tie into an older line of a smaller size. The reducing coupler makes that step in a straight run: the 110 mm pipe is cemented into the larger socket and the 90 mm pipe into the smaller one, with no branch and no change of direction.
Water speeds up as it passes into the smaller pipe, so designers usually place reductions where flow has already dropped. On site, clean and deburr both pipe ends, cement each socket in turn, and keep the two pipes aligned while the joints set. The fitting's rating is 10 bar at 20°C across a 0 to 50°C temperature range.
What to Specify When Ordering
- Sizes: 110 mm and 90 mm outside-diameter uPVC pipe.
- Joint type: solvent-cement pipe on both sides.
- Quantity: one per size change on the route.
- If a branch is also needed at the reduction point, specify a reducing tee instead.

Frequently Asked Questions
What sizes does the Reducing Coupler PVC skt scj 110x90mm-P connect?
The Reducing Coupler PVC skt scj 110x90mm-P connects a uPVC pipe of 110 mm outside diameter to one of 90 mm outside diameter. Both ends are female sockets joined with solvent cement in a straight line.
How is the 110 x 90mm reducing coupler different from a reducing tee?
The 110 x 90mm reducing coupler changes pipe size in a straight run with no side outlet, whereas a reducing tee also creates a branch. Use the coupler where the line simply continues at the smaller size.
What pressure is the 110 x 90mm PVC reducing coupler rated for?
The 110 x 90mm PVC reducing coupler is rated 10 bar at 20°C and suits water from 0 to 50°C. Since PVC carries less pressure as temperature rises, the working pressure should be checked against actual service conditions.
Is the Reducing Coupler PVC skt scj 110x90mm-P suitable for drinking water?
Please confirm with us whether the Reducing Coupler PVC skt scj 110x90mm-P suits your drinking-water application before ordering. Mention the intended use when you enquire through the contact page, and ask what documentation is available for the batch you are offered.
Who supplies the 110 x 90mm PVC reducing coupler?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, supplies the 110 x 90mm PVC reducing coupler to schools, WASH programmes, contractors and dealers in India and international markets, and can include it in a combined fittings quotation.
