5. Insert the armour cone (5a or 5b) into the entry item (2) and pass the
cable through them and the resin dam until the braid or armour contacts
the cone and make sure it is evenly spaced around it. Tighten the body
(6) to lock the braid or armour. Do not tighten the outer seal nut at this
stage. (On PB variants the earthing device automatically makes contact
with the lead sheath).
Fit the thread shield over the entry threads to protect them prior to
installing the resin.

1. The PX2K-REX type cable gland is supplied as a Universal Kit with two armour cones, the grooved
armour cone (5a) is suitable for Strip Armour, Tape Armour and Braided Cables, and the stepped cone
(5b) is suitable for Wire Armour (SWA) cables. The PX2KX-REX gland only has one cone (5a) and the
PX2KW-REX only has one cone (5b). (PB Variants have an earthing device for the lead sheath).

2. Separate the gland components by removing the body and outer seal nut assembly. Pass the body
and outer seal nut assembly (6),(8), and the AnyWay clamping ring (7) over the cable, outer seal nut
first.

3. Prepare the cable by stripping back the outer sheath and braid / armour to suit the equipment.
Expose the braid or armour further so that it can be formed around the armour cone by cutting back
the outer sheath by a length “L”. This length varies slightly depending upon cable diameter, but typical
values are shown below. The inner sheath should be long enough to just pass through the resin dam
when installed. (Typical length of inner sheath is shown as ‘M’ below.) On lead sheathed cables, the
lead sheath should be long enough to just pass through the armour cone when installed.

6. Refer to ‘RapidEx Resin’ assembly instructions to fill the connector Compound Tube

with the required amount of resin (1). The resin should not be mixed or applied at
temperatures below 5°C (40°F).

Resin Dam

contact against

Ensure Resin Dam is
in position in the
gland and making a
good seal against the
inner sheath.

Do not disassemble the gland to inspect the Resin Dam, diagrams

4. Remove any bedding or fillers from around the cable cores. If the cable cores have screens, these
should be unravelled and then twisted together to form a single core.
This single core and/or any drain wires present should be sleeved with some heat shrink tubing.

Electrical tape MUST be wrapped around the tips of the
cable cores. This is to ensure the cable cores are
together and also to cover any sharp edges that could
potentially tear the Resin Dam during installation.

7. Once the resin has cured remove the thread shield, loosen the body and remove the assembly
from the entry item. Fit the entry item into the equipment.

8. Re-install the assembly into the entry item and fully tighten the body (6) onto the entry item (2).
Tighten the outer seal nut assembly (8) until it comes to an effective stop. This will occur when :-

A) The outer seal nut has clearly engaged the cable and cannot be further tightened
without the use of excessive force by the installer.
B) The outer seal nut is metal to metal with the body of the gland (6).
