Cable Gland/Through-Connector RAYTECH BARNEY MUFA Przelotowa Gelbox IP68

RAYTECH BARNEY MUFA Przelotowa Gelbox IP68 is a through-type cable gland and gel-filled connector engineered to provide a watertight transition for cables. The device uses an internal silicone-based gel sealing system to protect cable passages from water, dust and corrosion while maintaining mechanical flexibility. Designed for outdoor and underground installations, the gelbox supports service entries, junction points and repair work where an IP68-rated barrier is required.

Advantages

The gel-filled design creates a continuous seal around cables of varying diameters without the need for heat-shrink sleeves or special tools, simplifying installation and reducing downtime. The IP68 protection rating ensures long-term resistance to immersion and ingress of particulates, and the flexible gel maintains cable integrity while allowing for movement and vibration. The unit is compact, lightweight and suitable for use with common power and communication cables.

Suitable for

• Outdoor cable entries and terminations
• Underground cable passages and pits
• Temporary and permanent cable repairs
• Service junctions for power and telecommunications

Key specifications

• Protection level: IP68 (immersion and dust-tight protection)
• Sealing medium: silicone-based gel for long-term waterproofing
• Type: through-type cable gland / gelbox for inline cable passage
• Compatibility: suitable for round electrical and communication cables with differing diameters
• Mechanical characteristics: flexible gel joint that accommodates cable movement and vibration
• Application environment: suitable for outdoor, underground and enclosed spaces

How to use

Prepare the cable by ensuring the outer sheath is clean and dry; remove any sharp edges or debris. Open the gelbox according to the product’s clamshell or split-body design, insert the cable through the gel chamber and position the section to be sealed within the gel. Close the unit securely to compress the gel around the cable, forming a continuous watertight seal. Verify the enclosure is fully closed and any locking clamps or fasteners are engaged. No heating or special tooling is required for the sealing process.

Usage recommendations

For best performance, select a gelbox size that matches the cable diameter range and follow installation checks for mechanical strain relief and secure mounting. Avoid exposing the sealed joint to sharp objects or prolonged abrasive contact. When used in underground installations, ensure the surrounding environment is free from excessive chemical exposure that could affect the cable sheath over time.
