Product Details
Overview
This HDPE butt fusion reducing coupler connects HDPE pipes of different diameters in a straight pipeline. Its reducing profile provides a transition between the larger and smaller pipe sizes.
Available sizes are listed above, with SDR11, SDR13.6 and SDR17 options. Please confirm the required size and SDR when placing your order.
Ordering Information
To request a quotation, please provide:
- Required size: large end × small end (mm)
- SDR rating: SDR11, SDR13.6 or SDR17
- Quantity for each size
- Delivery destination
- Any specific project requirements
We will confirm availability and provide pricing and an estimated lead time.
Applications & Installation
Typical Applications
Suitable for HDPE pipeline systems where a straight transition is required between two different pipe diameters, including water supply, irrigation and industrial piping projects.
Butt Fusion Jointing
The fitting is joined by butt fusion using compatible HDPE welding equipment. Pipe ends and fitting ends should be properly faced, aligned, heated and fused according to the applicable installation procedure.
Project Selection
Select the reducing size and SDR rating to match the pipeline design. Send us the required large-end size, small-end size, SDR and quantity for quotation and availability confirmation.
Frequently Asked Questions
What SDR ratings are available?
SDR11, SDR13.6 and SDR17 are available for this product series. Confirm the required SDR together with the pipe sizes when requesting a quotation.
How do I specify the reducing coupler size?
Specify the larger outside diameter first and the smaller outside diameter second, for example 160 × 110 mm.
