    Grey cable gland with a PG21 thread (12 mm long) and a compression nut. It seals one round cable with an outer diameter of 13–18 mm – e.g. 5×4–5×6 mm² or 4×10 mm² power cables. Protection IP68 (EN 60529).

  • Product description

    Cable gland with nut and seal | PG21 | for cable Ø13–18 mm | grey | IP68 | ES-PG21

    ES-PG21 is a grey PG21 cable gland with a compression nut and seal. It is screwed into a PG21 threaded hole in an enclosure or panel and tightened by hand and with a spanner. When the nut is tightened, the seal grips one cable with an outer diameter of 13–18 mm and closes the gap between the cable and the enclosure.

    Key point:
    PG21 is intended for thicker power cables: the Ø13–18 mm range often matches 5×4–5×6 mm² or 4×10 mm² cables (a guide only – the outer diameter decides) feeding EV chargers, heat pumps and sub-distribution boards. IP68 keeps outdoor and damp-room entries tight. The grey colour suits light grey panels and boxes, so the entry blends in with the enclosure.

    How it works

    Installation. With the power off, the gland is screwed into the PG21 hole and tightened by hand, then with a spanner; the cable is passed through the loosened nut.

    Operation. Turning the nut compresses the seal around the cable sheath – it fits evenly around the Ø13–18 mm cable and holds it at the same time.

    Result. A tight IP68 entry to EN 60529: dust stays out and the entry withstands continuous immersion under the conditions specified by the manufacturer.

    Why choose ES-PG21?
    A 5 mm wide range (Ø13–18 mm) lets one size serve several power-cable cross-sections, and the DIN 40430 thread (outer diameter 28.3 mm) fits standard PG21 holes.

    Main functions

    • IP68 sealing – protection against dust and continuous immersion (EN 60529).
    • Cable retention – the tightened nut reduces pull on the terminals.
    • PG21 thread – for standard PG21 holes, thread outer diameter 28.3 mm.
    • Range Ø13–18 mm – e.g. 5×4–5×6 mm² or 4×10 mm² power cables.
    • Thread length 12 mm – wall thickness and room for a locknut can be checked in advance.
    • Grey colour – matches light grey panels and boxes.

    Where is it used?

    • Supply entries of EV charging stations
    • Connection of heat pumps and boiler-room equipment
    • Supply cable entries of sub-distribution boards
    • Terminal boxes of compressors and larger motors
    • Construction-site and temporary boards
    • Outdoor cabinets next to buildings and car parks

    Use by need

    For EV charger installers.
    The charger supply cable often falls within the Ø13–18 mm range, so the entry into the outdoor board is sealed to IP68.
    For designers.
    The size is easy to compare with the IP68 grey series 00872 (PG21, Ø13–18 mm); for a metric hole – Haupa 250050 (M25×1.5, Ø13–18 mm).
    For facility managers.
    In outdoor cabinets and car-park equipment an IP68 entry reduces the risk of water getting into the board.

    Practical application

    If you are installing an EV charger at a house and the supply cable enters the outdoor board from below with an outer diameter of about 16 mm, ES-PG21 is the right size: screw it into the PG21 hole in the bottom of the board, pass the cable through, tighten the nut by hand and with a spanner – the entry is sealed and the cable is held.

    Pros

    • IP68 to EN 60529
    • Clear range Ø13–18 mm for one PG21 size
    • Thread length specified – 12 mm
    • Tightened by hand and with a standard spanner
    • CE, SGS, RoHS according to supplier data
    • Also available in the other colour – ES-PG21B (black)

    Cons / limitations

    • Limited range: for a cable thinner than Ø13 mm choose ES-PG19 (PG19, Ø12–15 mm), for one thicker than Ø18 mm – ES-PG25 (PG25, Ø16–21 mm).
    • One gland – one round cable; not suitable for a flat cable or several wires.
    • Material and operating temperature are not given in our data – check before buying for hot or chemically aggressive environments.
    • A PG21 thread is not compatible with a metric M25 hole – for a metric hole choose Haupa 250050 (M25×1.5, Ø13–18 mm).
    • Not a fire barrier – it does not replace fire-rated cable penetrations through fire walls.

    Safety and installation notes

    • Work in a panel or box only with the power disconnected and absence of voltage verified.
    • After drilling, remove all swarf from the enclosure – it can cause a short circuit.
    • Drill a plain hole to the thread outer diameter of 28.3 mm – an oversized hole does not ensure sealing.
    • Tighten first by hand, then with a spanner until the cable no longer moves in the seal; do not overtighten the thread.
    • Route the cable from below or with a drip loop so that water does not run along the cable to the gland.

    Quick selection guide

    PG21 thread (Ø 28.3 mm)
    Cable Ø13–18 mm
    IP68, thread length 12 mm
    Grey, ES-PG21
    Suitable when you need:
    • a tight entry for one cable with an outer diameter of 13–18 mm
    • an IP68 entry outdoors, in basements or damp rooms
    • an entry that matches a light grey panel or box
    Check before use:
    • The cable outer diameter with a calliper – it must be 13–18 mm.
    • The hole type: threaded PG21 or a plain Ø 28.3 mm hole (a locknut is then needed – its inclusion is not stated in our data).
    • The environment – material, operating temperature and UV resistance are not given in our data.
    Important reminder: The gland seals and holds one cable, but it is not a fire barrier: cable penetrations through fire walls need separate fire-stopping solutions.

    FAQ

    What cable size does ES-PG21 fit?
    A cable with an outer diameter of 13–18 mm – measure the sheath, not the conductor cross-section in mm².
    Is ES-PG21 suitable for a 5×6 mm² cable?
    Often yes – the outer diameter of such a cable usually falls within 13–18 mm, but it depends on the cable type and manufacturer, so measure it before buying.
    What hole size should I drill for a PG21 gland?
    A plain hole must match the PG21 thread outer diameter – 28.3 mm (DIN 40430); a locknut is needed on the inside.
    How does ES-PG21 differ from ES-PG21B?
    Only in colour: ES-PG21 is grey, ES-PG21B is black; thread, range and IP68 are the same.
    Is ES-PG21 suitable for continuous use under water?
    IP68 to EN 60529 covers continuous immersion, but the exact depth and duration are set by the manufacturer – they are not given in our supplier's data.
    What material is the gland made of and what is its operating temperature?
    The supplier has not specified these, so we do not guarantee them – for heat or chemicals, consult us before buying.
