    Black cable gland with a PG25 thread (12 mm long) and a compression nut. It seals one round cable with an outer diameter of 16–21 mm – e.g. 5×6–5×10 mm² or 4×16 mm² power cables. Protection IP68 (EN 60529). PG25 is not a DIN 40430 size – measure the hole thread before ordering.

  • Product description

    Cable gland with nut and seal | PG25 | for cable Ø16–21 mm | black | IP68 | ES-PG25B

    ES-PG25B is a black PG25 cable gland with a compression nut and seal. It is screwed into a PG25 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 16–21 mm and closes the gap between the cable and the enclosure.

    Key point:
    PG25 is a non-DIN 40430 size between PG21 and PG29, so it is the right choice when the enclosure or equipment already has a PG25 thread. The Ø16–21 mm range often matches 5×6–5×10 mm² or 4×16 mm² power cables (a guide only – the outer diameter decides). The thread must be measured before ordering. Black is often chosen for dark enclosures, machines and equipment where a light entry would stand out.

    How it works

    Installation. With the power off, the gland is screwed into the PG25 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 Ø16–21 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-PG25B?
    It lets you bring a thick power cable tightly into an existing PG25 hole without re-drilling, and IP68 keeps outdoor and damp-room equipment sealed.

    Main functions

    • IP68 sealing – protection against dust and continuous immersion (EN 60529).
    • Cable retention – the tightened nut reduces pull on the terminals.
    • PG25 thread – a non-DIN 40430 size, so measure the hole before ordering.
    • Range Ø16–21 mm – e.g. 5×6–5×10 mm² or 4×16 mm² power cables.
    • Thread length 12 mm – wall thickness and room for a locknut can be checked in advance.
    • Black colour – matches dark enclosures, machines and equipment.

    Where is it used?

    • Repair of existing boards and equipment with a PG25 thread
    • Supply cable entries of distribution boards
    • Power supply of industrial equipment and machine tools
    • Compressor rooms, boiler rooms and pump stations
    • Outdoor and metering cabinets
    • Equipment enclosures for cables with an outer diameter of 16–21 mm

    Use by need

    For industrial equipment electricians.
    When a machine-tool or compressor enclosure has a PG25 hole, ES-PG25B lets you seal a Ø16–21 mm supply cable without modifying the enclosure.
    For service engineers.
    A worn PG25 entry can be replaced with a new IP68 gland after measuring the thread with a calliper.
    For facility managers.
    In boiler rooms and pump stations an IP68 entry protects boards from water and moisture.

    Practical application

    If you are replacing a damaged machine-tool supply entry with a PG25 thread in a compressor room and the cable outer diameter is about 19 mm, first compare the hole thread and the ES-PG25B thread with a calliper; if they match, screw in the gland, pass the cable through and tighten the nut by hand and with a spanner.

    Pros

    • IP68 to EN 60529
    • Clear range Ø16–21 mm for one PG25 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-PG25 (grey)

    Cons / limitations

    • Limited range: for a cable thinner than Ø16 mm choose ES-PG21B (PG21, Ø13–18 mm), for one thicker than Ø21 mm – ES-PG29B (PG29, Ø18–25 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.
    • PG25 is not a DIN 40430 size – the thread outer diameter is not given in our data, so the hole and thread must be measured with a calliper before ordering.
    • 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.
    • PG25 is not a DIN 40430 size – before drilling or ordering, measure the thread with a calliper and compare it with the mating part.
    • 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

    PG25 thread (measure)
    Cable Ø16–21 mm
    IP68, thread length 12 mm
    Black, ES-PG25B
    Suitable when you need:
    • a tight entry for one cable with an outer diameter of 16–21 mm
    • an IP68 entry outdoors, in basements or damp rooms
    • an entry that matches a dark enclosure, machine or device
    Check before use:
    • The cable outer diameter with a calliper – it must be 16–21 mm.
    • The hole thread with a calliper – PG25 is not a DIN 40430 size, so compare the dimensions with the gland.
    • 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-PG25B fit?
    A cable with an outer diameter of 16–21 mm – measure the sheath, not the conductor cross-section in mm².
    Is ES-PG25B suitable for a 4×16 mm² cable?
    Often yes – the outer diameter of such a cable usually falls within 16–21 mm, but it depends on the cable type and manufacturer, so measure it before buying.
    What hole size does a PG25 gland need?
    PG25 is not a DIN 40430 size, so we do not state a hole diameter – measure the gland and hole threads with a calliper; a PG21 or PG29 gland will not fit a PG25 hole.
    How does ES-PG25B differ from ES-PG25?
    Only in colour: ES-PG25B is black, ES-PG25 is grey; thread, range and IP68 are the same.
    Is ES-PG25B 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.
