This IP68 marine grade fitting solves the problem of providing a waterproof gland which will allow you to pass a cable from the outside of your motorhome to the inside even though the cable is already fitted with a connector which has a much larger diameter than the cable itself.This version is made from UV-stable grey nylon.

The new DG series cable glands with their attractive, low profile shape replace the well known M Series cable glands; the DG21P replaces the A1SS1P from the previous range.

The gland is provided with a set of special rubber bushes which have a split from the perimeter to the central cable holes, so that the cable connector can be passed through the large hole in the cap of the gland before the bush is placed over the cable. The cap and the bushes are tapered so that when the cap is tightened down the rubber bush is compressed and the slit is closed tightly while at the same time the cable is gripped tightly in the central hole.

Three bushes are included thus providing a choice of hole sizes to suit your cable diameter.

An advantage of the design is that it is fitted entirely on one side of the opening so there is no nothing to tighten up on the other side which otherwise can be a problem when there is an intervening cavity, for instance in double-skinned GRP roofs and side panels.

The 21 mm central hole in the base and cap will allow a large connector up to this size to pass through and the bushes will provide a water-tight seal on cables from 4.5mm to 9mm outside diameter. The gland is available in aluminium or plastic material (see the alternatives panel). We can also supply larger models of the same design for bigger cable and connectors - although our standard gland should be all you would need for typical motorhome uses.

  • Made from UV-stable grey nylon
  • Takes cables from 4.5mm - 9mm complete with connectors up to 21mm.
  • Complete with three rubber bushes and flexible sealing washer for the backplate, and stainless steel fixing screws and bolts.
  • The gland can be re-opened at any time if it is necessary to disconnect or remove the cable and connector.
  • Overall size of the fitting, approx.: diameter 49mm; total height of base and cap 19mm.
  • Weight: 150gm

Why we rate it GREAT STUFF!

Note that this describes the SS1 glad which has now been superseded by the DG21P; the new gland has a lower, more rounded shape and even better waterproofing, being rated at IP68.

When we installed reversing cameras on our motorhome the system came with 4-pin cabling which was already complete with connectors. Although this makes the system plug-and-play with no risks of connectors being fitted with incorrect wiring or poor connections, it does make it difficult to reconcile the larger hole needed for the connector with the small opening needed to seal against the cable.

Large dollops of sealant might suffice of course but this would look unsightly, might not provide a reliable seal and it is difficult to remove the cable and connector afterwards, should that be required.

This gland solved all of these problems and although it is overall quite a large fitting it provides a very neat and professional-looking solution.

See the article about how we used these glands for the installation of our own reversing cameras, and see more pictures in a slideshow: Waterproof glands for our reversing cameras
