IP68 gel cable connectors for reliable cable connections under extreme conditions


RELICON Reliseal gel-filled cable connectors: for the toughest demands

gel filled cable joint Reliseal

RELICON Reliseal IP68 gel cable connectors are secure and robust partners for the most extreme conditions. The straight-through joints consist of a solid polypropylene shell (PP) filled with RELICON gel. These gel connectors are suitable for jointing on polymeric wires made of PVC, XLPE, PE, EPR, etc.

RELICON Reliseal fulfils the highest requirements for electrical installations and offers mechanical protection, insulation and sealing in one work step. Installers save time and require no special installation tools. Suitable for application in low-voltage electrical networks, underground, submerged, outdoors, indoors and in wiring ducts to repair damaged cable exposed to water or vibration.


RELICON Relilight gel-filled cable connectors: the compact protector

Gel-filled cable joints Relilight

RELICON Relilight connectors with IP68 protection classification are specially designed for lighting installations, with a specific focus on LED lighting.

They are tested according to DIN EN 60998-2-1:2004. The sleeves are flame retardant according to UL94 V0. Depending on the model and connector type, Relilight is suitable for straight-through and branch connections and for jointing on polymeric wires made of PVC, XLPE, PE, EPR etc.

The silicone-based RELICON gel pre-filled in the sleeves provides insulation, sealing and mechanical protection in one step and reduces the total cost of installation. Ideal for application in low-voltage networks, for outdoor lighting installations, connections underground, submerged, outdoors, indoors and in wiring ducts.

RELICON Relifix gel cable connectors: the universal sleeve

gel-filled cable joint Relifix

RELICON Relifix is quick and easy to install. The sleeves are provided with a film hinge and are made from thick-walled and impact resistant polypropylene (PP).

For application in low-voltage networks underground, submerged (to 1.3 m), outdoors, indoors and in wiring ducts. A separate strain relief accessory is available where required, or alternatively, Reliseal or Relilight can be installed.

FAQ – Frequently Asked Questions

Do gel joints also protect against the ingress of foreign bodies (e.g. plant roots)?

Many gel sleeves do not offer complete protection. However, the RELICON Reliseal and Relilight gel joints do. No foreign bodies such as roots can penetrate. The Reliseal and Relilight gel sleeves have protection class IP68. The first digit indicates how resistant the housing is to the ingress of foreign bodies. The "6" is the highest protection available. This indicates that the sleeve is fully protected against penetration through the enclosure, like touching, debris, dust or roots. Reliseal and Relilight are thus optimally protected against root ingrowth.

Can gel joints be used in water?

In principle, gel joints can also be used in water, if the assembly is carried out correctly. RELICON gel joints are protected against water penetration for an indefinite period of time, even when completely submerged. In the case of the Reliseal gel joint, even in water depths of up to 10 metres.

Gel joint installation cannot be performed under water. The complete installation must be carried out "dry". However, the gel joints can be submerged in water directly after installation at depths of 1 to 10 metres, depending on the type.

What does strain relief mean?

Strain relief refers to a mechanical protective device on electrical cables. With the help of strain relief, the connection between electrical cables is protected against tensile forces. Tensile forces occur, for example, during excavation work when the cable is accidentally pulled, or when a cable is installed vertically or on a slope and is subject to gravity over time. The RELICON Reliseal and RELICON Relilight gel sleeves include integrated strain relief.

What regulations do the gel joints meet?

HellermannTyton gel joints are either tested according to the European guidelines of energy companies (EN 50393) or have the IP68 classification.

Gel joints can be reopened but not reused – what does this mean?

Our gel joints can be opened post installation, e.g. for visual inspection or for changing the cable configuration. However, it is not possible to reuse the same joint for a new installation. Closing a sleeve causes the gel to build up pressure around the cable sheath or conductor. This creates a contact surface that is only correct the first time it is closed. Accordingly, gel that has formed during the initial assembly cannot be used again, because the necessary pressure cannot be built up.

Is the gel harmful to the skin?

No, but if you come into contact with the gel, we recommend washing it off with plenty of soap and water. Do not use solvents or thinners.

What is crumb resin?

Crumb resin is the name given to a potting compound that can be easily removed after curing. This is possible by hand without the use of tools. In the process, the cured potting compound becomes "crumbly". Crumb resin is a 2-component resin based on hydrocarbon resin. These hydrocarbon resins are without hazardous substances. HellermannTyton offers the two crumb resins KH100 and KH67 in its portfolio.
