REPL RHCSG Heat Shrink Cable Sealing Gland | 19-69mm
REPL RHCSG Heat Shrink Cable Sealing Gland | 19-69mm
Product Code: REPL RHCSG
Available Models: RHCSG-4 | RHCSG-5
The REPL RHCSG Heat Shrink Cable Sealing Gland provides a watertight and fume-tight cable entry seal where cables enter connection boxes, electrical enclosures or pass through bulkheads. Designed for unarmoured cable sealing, the three-part gland combines a rigid threaded body, nylon nut, rubber O-ring and adhesive-lined heat shrinkable seal to provide reliable environmental protection around the cable sheath. Two RHCSG gland sizes accommodate cables with overall diameters from 19mm to 69mm, with pressure sealing capability up to 170kPa (1.7 bar).

The REPL RHCSG Heat Shrink Cable Sealing Gland is designed to create a durable watertight and fume-tight seal around cables entering connection boxes, cable boxes, electrical enclosures and bulkheads. Suitable for sealing unarmoured cables, the RHCSG combines mechanical enclosure sealing with an adhesive-lined heat shrink connection around the cable sheath, helping prevent moisture and fumes passing through the cable entry point.
The gland consists of three primary components: a rigid threaded body, nylon retaining nut and rubber O-ring. The nut is tightened onto the threaded body to compress the O-ring and establish a seal against the wall of the box or bulkhead. The integral heat shrinkable section is then recovered directly onto the cable sheath to complete the cable entry seal.
For enhanced moisture protection, the heat shrink section incorporates an internal hot-melt adhesive coating. During installation, heating causes the tube to recover around the cable while activating the adhesive, creating close contact between the heat shrink material and cable oversheath.
The RHCSG range consists of two sizes, RHCSG-4 and RHCSG-5, collectively accommodating cable overall diameters from 19mm to 69mm. The glands provide pressure sealing up to 170kPa (1.7 bar) and are suitable for continuous operating temperatures from -55°C to +90°C.

Watertight & Fume-Tight Cable Entry Sealing
The REPL RHCSG is designed to seal the interface between a cable and the wall of a connection box, cable box, electrical enclosure or bulkhead. The gland provides two complementary sealing functions: the O-ring seals the gland body against the enclosure, while the recovered heat shrink section seals directly around the cable sheath. This arrangement helps create a continuous environmental seal through the cable entry point.
Adhesive-Lined Heat Shrink Seal
The heat shrinkable section incorporates an internal coating of hot-melt adhesive. When correctly heated during installation, the polyolefin tube recovers tightly around the cable sheath while the adhesive softens and flows into the interface. Once cooled, this produces a close-fitting moisture-resistant seal between the gland and cable.
Mechanical Bulkhead & Enclosure Seal
The rigid gland body passes through the prepared cable entry aperture and is secured using the nylon nut. Tightening the nut compresses the rubber O-ring against the wall of the connection box or bulkhead, creating the mechanical portion of the gland seal before the heat shrink section is recovered onto the cable.
Range-Taking RHCSG Cable Gland Design
Only two RHCSG sizes are required to cover cables with overall diameters from 19mm to 69mm. RHCSG-4 uses a 51mm drill size and RHCSG-5 uses a 90mm drill size, allowing the appropriate gland to be selected according to cable and enclosure dimensions.
REPL RHCSG Applications
✔ Cable entry sealing into electrical connection boxes
✔ Cable sealing through bulkheads and equipment walls
✔ Unarmoured power cable sealing applications
✔ Medium voltage cable entry sealing
✔ Cable boxes and electrical enclosures
✔ Utility and power distribution equipment
✔ Industrial electrical installations requiring moisture protection
✔ Cable entries requiring watertight and fume-tight sealing
RHCSG Construction & Cable Sealing
The REPL RHCSG cable sealing gland uses a simple three-part assembly designed to form a secure seal both at the enclosure wall and around the cable sheath. This combination makes the gland suitable for applications where protection against moisture and fumes is required at the cable entry point.

How the REPL RHCSG Cable Sealing Gland Works
The gland body is positioned through the prepared cable entry aperture with the O-ring located between the gland and enclosure surface. The nylon nut is then tightened onto the threaded body, compressing the O-ring to create a seal between the gland and the connection box or bulkhead.
Once the cable has been positioned through the gland, the heat shrinkable section is evenly heated and allowed to recover onto the cable sheath. During recovery, the internal hot-melt adhesive activates and forms the moisture seal between the cable oversheath and heat shrink tube.
Correct product selection should take account of the cable outside diameter, gland dimensions, available cable entry aperture and installation conditions. Where sizing is uncertain, contact Thorne & Derrick for assistance before ordering.
Selecting RHCSG-4 or RHCSG-5
The REPL RHCSG range is supplied in two sizes to accommodate cables across the manufacturer’s stated overall diameter range of 19mm to 69mm. Selection should be based on the actual cable outside diameter together with the required gland body, recovered tube and enclosure entry dimensions.
RHCSG-4 has a 45mm as-supplied heat shrink tube diameter, 19mm fully recovered tube diameter, 41mm body/nut internal diameter and requires a 51mm drill size.
RHCSG-5 has a 70mm as-supplied heat shrink tube diameter, 36mm fully recovered tube diameter, 74mm body/nut internal diameter and requires a 90mm drill size.
For applications where the cable diameter falls within an overlapping or uncertain dimensional area, the complete installation dimensions should be checked before final gland selection.
