AstralPool Cable gland plug set - 440301007

Cable gland plug set 4403010076

The cable gland plug set 4403010076 is a replacement sealing kit for pool projector cable entries. It is designed to close unused cable glands or seal passages in projector niches and junction boxes, maintaining the watertight integrity of the underwater lighting installation after repairs, upgrades or cable changes.

Function of the cable gland plug set

In pool lighting systems, every opening in a niche or junction box is a potential path for water ingress. When a cable entry is no longer used, or when an additional gland opening must be sealed, dedicated plugs are required to close the port securely. The cable gland plug set 4403010076 provides the correct plugs and sealing elements to block these openings and help keep the projector compartment dry.

Using the correct plug set is important to preserve the original sealing design of the projector niche and to avoid improvised solutions that may not withstand long term immersion and pressure changes.

Design and compatibility

The cable gland plug set 4403010076 is engineered for use in compatible pool projector niches and housings. The plugs are dimensioned to fit the dedicated threaded openings usually used by vertical or horizontal cable glands, and include sealing components that compress against the housing when tightened.

• Replacement plug kit for cable entries using reference 4403010076.
• Thread and diameter adapted to projector niche openings.
• Sealing elements designed for submerged pool environments.

Before installation, the projector documentation should be checked to confirm that this plug set is listed as a compatible spare part for the specific niche or housing model.

Typical use during renovation and maintenance

The cable gland plug set 4403010076 is often used during lighting renovations, when existing cable routes are changed or when a niche has more openings than needed. By closing unused entries with correctly sized plugs, you help protect the internal space against water ingress and reduce the risk of corrosion at electrical connections.

• Sealing unused cable glands after rerouting or removing cables.
• Closing spare openings in projector niches or junction boxes.
• Restoring watertightness during projector refurbishment.

The set is also useful as a service spare, allowing technicians to replace damaged or missing plugs whenever a niche is opened for inspection or repair.

Installation guidelines

Installing the cable gland plug set 4403010076 follows the same principles as mounting a cable gland. The plug is threaded into the prepared opening and tightened to compress the seal. Correct torque and positioning are essential to achieve a reliable seal without stressing the niche or deforming the housing wall.

• Clean the opening and remove any old sealant or damaged parts.
• Screw the plug into the threaded port by hand to avoid cross threading.
• Tighten carefully until the sealing surface is evenly compressed.

All work on pool lighting should be performed by a qualified installer who follows local regulations and the manufacturer instructions for the projector, niche and junction box.

When to replace cable gland plugs

Over time, plug seals can harden, crack or lose elasticity due to temperature changes, water chemistry and mechanical stress. Replacing ageing or damaged plugs with a new cable gland plug set 4403010076 helps prevent slow leaks that might only become visible after long periods of use.

• Recommended when existing plugs show cracks or visible deformation.
• Advised after accidental damage during cable replacement or handling.
• Suitable as a preventive replacement during complete projector refurbishment.

Using the correct plug set supports long term watertightness of the pool lighting system and helps protect the projector and electrical connections throughout the swimming season.
