Adhesives & Sealants

Electrical resin gels and sealants are insulating compounds poured or squeezed into joints and enclosures to keep out moisture, protecting connections in damp, outdoor and underground locations. We stock Raytech Magic Resin Gel in 1 litre and 2 litre packs and Magic Gel Sprint in a 450ml pack.

Unlike hard-setting resin, gel sealants stay soft so the joint or junction box can be re-entered later for testing or alterations. Trade customers get account pricing, and stock gel ordered before the 5pm cut-off ships for next working day delivery in Northern Ireland and the Republic of Ireland.

How to choose a resin gel or sealant

Water getting into a connection is one of the most common causes of faults on outdoor and underground circuits. Gel sealants fill the space around terminals and cable entries so moisture has nowhere to go.

Typical applications

Sealing connections inside junction boxes on external walls or in ground-level locations
Protecting terminations for garden, landscape and outdoor lighting
In-line joints on low voltage cables in damp or wet conditions
Filling enclosures exposed to condensation

Choosing the pack size

Work out the internal volume of the box or joint shell to be filled, then allow a little extra. The 450ml Magic Gel Sprint suits smaller boxes and single joints, while 1 litre and 2 litre packs of Magic Resin Gel cover larger enclosures or several jobs. Check the manufacturer's data for coverage and suitable applications.

Gel or hard resin?

Re-enterable gel is ideal when future access is likely, as it can be removed to reach terminals and then topped up. Hard-setting resin, as used in SWA cable joint kits, creates a permanent encapsulated joint that is not designed to be reopened. Choose based on whether the connection must remain accessible.

Application tips

Make and test the connections first, ensure the box is clean and dry, then fill slowly so the gel flows around all terminals without trapping air. Close the lid as instructed. Follow the safety data and the manufacturer's instructions, and check current wiring regulations regarding accessibility of connections.

FAQ's Ask Your Own Question

What is re-enterable gel used for in electrical work?: Re-enterable gel is used to seal electrical connections against water while still allowing access later. It is poured into junction boxes, joint shells and enclosures, where it surrounds the terminals and blocks moisture. When work is needed, the gel can be removed to reach the connections and then replaced or topped up.
How much resin gel do I need for a junction box?: Estimate the internal volume of the box, minus the space taken by terminals and cables, and choose a pack that covers this with some to spare. A small outdoor junction box may only need a 450ml pack, while larger enclosures or multiple boxes suit 1 or 2 litre packs. Check the manufacturer's coverage guidance.
Can resin gel be used on underground cable joints?: Gel sealants can be used to protect certain low voltage joints in damp or underground conditions, depending on the product and the joint enclosure. Check the manufacturer's approved applications before burying a gel-filled joint. For permanent underground joints on SWA cable, a hard-setting resin joint kit is the more common choice.
Is resin gel safe to handle?: Resin gels are designed for site use, but you should always read the product's safety data sheet before use. Wearing gloves and eye protection is good practice, and work should be carried out in a ventilated area. Keep the product away from children and store it as instructed by the manufacturer.
Does sealing a box with gel change its IP rating?: Filling a box with gel adds protection against moisture reaching the connections, but the enclosure's official IP rating is set by its manufacturer under defined test conditions. Use the gel as an extra safeguard, and still choose a box and glands with an IP rating suitable for the location.
Can I open a credit account to buy sealants and joint kits?: Yes, Meteor offers trade accounts with trade pricing, and credit accounts are available subject to approval.
