    Haupa 250072 is a light grey PG29 cable gland made of PA 6.6 polyamide, with lock nut. It seals one cable with an outer diameter of 18–25 mm – e.g. five-core 10–16 mm² power cables (a guide only – the outer diameter decides). IP68, operating temperature −40…+85 °C.

  • Product description

    Cable gland with nut and seal | PG29 | for cable Ø18–25 mm | light grey | IP68 | Haupa | 250072

    Haupa 250072 is a cable gland with a PG29 thread, compression nut, TPR sealing ring and lock nut. The PG29 thread outer diameter to DIN 40430 is 37 mm; this is a large size for heavy power cables of Ø18–25 mm, for example a building or equipment supply entry. When the nut is tightened, the ring grips the cable and the integrated strain relief holds it.

    Key point:
    A heavy supply cable is often brought into a panel or machine through an open hole or a wrongly sized gland – moisture and dust then reach the incoming terminals directly. Haupa 250072 is made for exactly this entry: for a Ø18–25 mm cable, with IP68, a lock nut and integrated strain relief that holds a heavy cable.

    How it works

    Installation. With the power off, the gland is inserted into a PG29 opening and secured from inside with the lock nut (thread length 10.8 mm), then the cable is passed through the loosened nut.

    Operation. As the nut is tightened with an SW42 spanner, the TPR sealing ring grips the Ø18–25 mm cable evenly, and the integrated anti-twist feature stops the gland from loosening under vibration.

    Result. An IP68 entry to EN 60529 – protection against dust and long-term immersion under conditions defined by the manufacturer (the exact depth and duration are not stated in Haupa data).

    What makes Haupa 250072 useful?
    A large pre-assembled gland for a PG29 opening with lock nut: the 10.8 mm thread length and SW42 spanner size allow firm tightening even on a thicker panel wall, and the Ø18–25 mm range covers a large share of 5×10–5×16 mm² cables.

    Main functions

    • IP68 sealing – protection against dust and long-term immersion.
    • Integrated strain relief – holds the cable and reduces pull on the terminals.
    • Anti-twist feature – the gland does not loosen under vibration.
    • PG29 thread – fits PG29 openings to DIN 40430; outer diameter 37 mm.
    • Range Ø18–25 mm – e.g. five-core 10–16 mm² power cables (a guide only – the outer diameter decides).
    • Halogen-free PA 6.6 – body and sealing ring are halogen-free, flammability class UL 94 V-2.

    Where is it used?

    • Supply cable entries of building and apartment panels
    • Outdoor incoming and metering cabinets
    • Connection of compressors, machine tools and larger pumps
    • Panels in heating substations and boiler rooms
    • Supply entries of EV charging points
    • Cable entries of temporary construction-site panels
    • Distribution panels in farm buildings

    Use by need

    For the designer.
    PG29, Ø18–25 mm, IP68 and SW42 – clear parameters for the specification when the panel already has PG openings.
    For the installing electrician.
    One gland for a heavy supply cable with the lock nut included – no hunting for separate parts on site.
    For the facility manager.
    An IP68 entry with strain relief reduces the risk of moisture or cable movement damaging the incoming terminals.

    Practical use

    If a 5×16 mm² cable with an outer diameter of about 23 mm enters an outdoor metering or distribution cabinet with a PG29 opening, Haupa 250072 will fit: insert it into the opening, secure it from inside with the lock nut, pass the cable through and tighten the nut with an SW42 spanner – the entry is sealed and the cable is held.

    Pros

    • Confirmed manufacturer data: Ø18–25 mm, SW42, thread length 10.8 mm
    • IP68 – a higher class than the IP67 series glands
    • Lock nut included, gland supplied assembled
    • Anti-twist feature – suitable for vibrating equipment
    • Halogen-free PA 6.6 and TPR, UL 94 V-2
    • Operating temperature −40…+85 °C

    Cons / limitations

    • This is a PG29 thread – it does not fit metric openings.
    • Limited range: for a cable thinner than 18 mm – Haupa 250050 (M25×1.5, Ø13–18 mm) for an M25 opening or 00872 (PG21, Ø13–18 mm) for a PG21 opening; for one thicker than 25 mm – 00902 (PG36, Ø22–32 mm).
    • One gland – one round cable; not for flat cables or several wires.
    • IP68 test conditions (depth, duration) are not stated in our data; it is not a fire barrier.

    Safety and installation notes

    • Work in a panel only with the power disconnected and the absence of voltage verified.
    • After drilling or punching, remove the swarf from the enclosure – it can cause a short circuit.
    • The wall must be thinner than the 10.8 mm thread length – otherwise the lock nut will not seat properly.
    • Tighten the nut with an SW42 spanner until the cable no longer moves in the ring; do not overtighten the plastic thread.
    • Additionally secure a heavy cable inside the panel and route it from below or with a drip loop.

    Quick selection guide

    PG29 (Ø 37 mm)
    Cable Ø18–25 mm
    IP68, −40…+85 °C
    SW42, with lock nut
    Suitable when you need:
    • to seal a heavy Ø18–25 mm power cable into a PG29 opening
    • an IP68 entry outdoors, in a basement or on vibrating equipment
    • a light grey entry on a grey cabinet or box
    Check before use:
    • The cable outer diameter with a caliper – it must be 18–25 mm.
    • That the opening is really PG29 (thread outer diameter 37 mm), not metric.
    • The wall thickness – it must be less than the 10.8 mm thread length.
    Important reminder: The gland seals and holds one cable, but it is not a fire barrier – it does not replace fire-rated cable penetrations.

    FAQ

    What cable size does Haupa 250072 fit?
    A cable with an outer diameter of 18–25 mm – measure the sheath, not the conductor cross-section.
    Does Haupa 250072 fit a metric M32 or M40 opening?
    No – it has a PG29 thread (outer diameter 37 mm); a metric opening needs a metric gland, an M25 opening – Haupa 250050.
    Is a lock nut included?
    Yes – according to distributor data the gland is supplied with a lock nut.
    What spanner size is needed?
    The nut takes an SW42 spanner.
    Is the gland halogen-free?
    Yes – Haupa specifies a halogen-free PA 6.6 body and TPR sealing ring; the O-ring is PVC.
    Can two cables be passed through it?
    No – the ring seals only one round cable; use a separate gland for each cable.
