Flexible Couplers
Description
Manufactured from EPDM elastomer and supplied with all-stainless steel worm drive clips the couplers provide a neat and easy solution for connecting pipework in drainage and other non-pressure applications.
The fittings are suitable for the following pipework connections:-
Imperial x Imperial, Metric x Metric, Imperial x Metric and other non-standard pipe sizes.
Pressure Rating
These fittings are not pressure rated and should not be used for pressure applications.
Sizing
Due to their flexible nature these couplers can accommodate minor pipework misalignment and variations in diameters.
The flexible fittings are suitable for both metric and near-similar sized imperial pipework. For example a 63mm coupler can also be used with 2" (60.3mm o.d.) imperial pipe.
The following table details the range of recommended pipe sizes that can be used for each fitting:-

Metric Pipe Size |
Imperial Pipe Size NB* |
Maximum Pipe Size |
Minimum Pipe Size |
| 25 mm | 3/4" (26.7mm) | 28 mm | 24 mm |
| 32 mm | 1" (33.6mm) | 35 mm | 31 mm |
| 40 mm | 1 1/4" (42.2mm) | 42 mm | 38 mm |
| 50 mm | 1 1/2" (48.3mm) | 51 mm | 47 mm |
