Made to Order - Large Standard Couplings
As the items are made to order to suit specific site requirements: please specify dimensions required when ordering.
- NB: The size range is an indication of size for pricing purposes only. Couplings are manufactured to meet customer requirements. Please consider that the size you request will be the maximum size that the coupling will be manufactured to. For ease of installation you may require a slightly larger size.
Standard Couplings
These couplings comply with the requirements of WIS 4-41-01 and are specifically designed for jointing pipes in sewerage, drainage and similar non-pressure applications where resistance to shear loads is required.
- On public sewers where couplings complying with WIS 4-41-01 are specified
- Repair and maintenance of existing pipelines
- Connections between pipes fo different materials or sizes (Bushes may be required in these circumstances)
- Making connections by the insertions of new junctions into an existing pipeline
- Reconnection of laterals on renovated sewers
- Introducing rocker or hinge pipes outside manholes or structures
- Jointing short or cut lengths of pipe
Bushes
Manufactured from synthetic elastomers and available in a variety of sizes and thicknesses to allow the Standard range of couplings to connect pipes which may have a considerable difference in their outside diameters.
They are used where the difference in the outside diameter of the pipes to be jointed exceeds 12mm and an Adaptor Coupling is not available.
Generally used singularly but multiple bush sets may be used.
Available in diameters up to 2000mm and in four thicknesses: 8mm, 16mm, 24mm, 32mm
- Note 1: The size range is an indication of size for pricing purposes only. Bushes are manufactured to meeting specific customer requirements
- Note 2: For bushes over 1000mm diameter please contact 01226 794045
Adaptor Couplings
Provide an inexpensive method of directly jointing pipes of differing outside diameters, without the need to use bushes. The most common application is for connecting PVC-u pipes to a variety of other pipe materials including vitrified clay. These couplings are also suitable for connecting other types of pipes including case iron and metal pipes (up to a maximum outside diameter of 420mm).
Pipe Couplings
Used in drainage systems to connect pipes where resistance to shear loads is not required.
Applications include:
- Repair of an existing drain by intertion of a new length of pipe
- Adaptor between pipes of difference material or manufacturers
- Jointing short lengths of pipe
End Cap
A reusable and flexible, easy to fit cap for permanent or temporary applications such as air testing waste or soil systems, capping or preventing dirt ingress.
Plumbing Range
Used for connecting smaller diameter pipes. The couplings are designed for connecting pipes with a similar outside diameter and the adaptors for connecting pipes of differing outside diameters.
Installation Tools
For pipelines up to and including 290mm OD, a Naylor 8mm nut driver (reference T0001) can be used to tighen clamping bands and shear bands (where present) firmly by hand (equates to recommended torque of 6-8 Nm).
For pipelines exceeding 290mm, a Naylor 8mm ratchet spanner (reference T0002), can be used to tighten clamping bands and shear bands firmly by hand (equates to recommended torque of 12-14 Nm).
Made to Order - Extra Wide Couplings
Naylor Extra Wide Couplings are used predominantly for jointing pipes with a diameter greater than 1000mm but they are available to suit pipes with an outside diameter of 200mm upwards.
Naylor Extra Wide Couplings have a width of 300mm which allows a greater tolerance when cutting larger diameter pipes. The increased width also accommodates the greater movement of the joints associated with the depths at which these larger diameter pipes are laid.
NB: The size range is an indication for pricing purposes only. Couplings are manufactured to meet customer requirements.
Chemical Couplings
The range of Hathernware chemically resistant Band-Seal couplings offers the chemical and process industries the advantage of a modern, mechanical, flexible jointing system for any plain end pipe system, including Naylor's Hathernware "Thermachem" range of thermal shock and chemically resistant pipes.
