Guagzhou Yinfu cable glands for pool equipment

Cable glands are small parts with a large job: they hold a flexible cable in place where it enters a housing and close the gap around it so water, dust and insects stay outside. Here you will find the Guagzhou Yinfu range as it is listed on this page, which centres on the PG7 size for thin cables of 5 to 7 mm. They are the kind of component that is rarely noticed until a control box, a light niche or a junction housing starts letting in moisture, at which point a replacement gland is usually the quickest and cheapest fix.

What a PG7 cable gland is

A gland of this type consists of a threaded body, a compression nut, a split sealing insert and, in most cases, a locknut for fixing the body into a panel from the inside. The cable passes through the body, the insert closes around it, and tightening the compression nut squeezes the insert onto the cable sheath. The result is a cable entry that grips the cable mechanically, so pulling on the lead outside does not transfer strain to the terminals inside, while the insert closes the opening around the sheath.

PG7 is one of the smallest sizes in the PG thread series, which continues upwards through PG9, PG11, PG13.5, PG16 and larger. The PG7 thread is intended for a panel hole of roughly 12.5 mm. Because the series is standardised, a PG7 gland will thread into any PG7 opening regardless of which housing it came from, which is what makes these parts useful as generic replacements.

A megfelelő méret kiválasztása

Two measurements decide whether a gland will work, and both are easy to check before ordering:

• Cable outer diameter – measure across the outer sheath, not across the individual conductors. The PG7 gland listed here covers 5 to 7 mm. A cable thinner than the stated minimum will not be gripped properly; a thicker one will not allow the nut to close.
• Thread size and panel hole – look at the existing gland or the opening in the housing. If the old part is still fitted, the size is often moulded into the body.
• Testhossz – the threaded section must be long enough to pass through the wall thickness of the housing and still accept the locknut.
• Number of cables – one cable per gland is the rule. Two leads forced through a single insert leave gaps on either side.
• Material compatibility – plastic glands are the usual choice around pools because chlorinated and salted water are hard on untreated metal.

Where these parts are used around a pool

Thin cables in the 5 to 7 mm range appear all over a pool installation, which is why a small gland such as the PG7 has so many applications. Typical places include the cable entry on pump and filtration control boxes, transformer enclosures for low-voltage lighting, the housings of timers and level switches, dosing and measuring equipment, sensor leads on heat pumps and heaters, and the junction boxes used to connect underwater lights above the water line.

Sealing inserts harden with age, with UV exposure and with repeated heating and cooling in an outdoor cabinet. Once the insert has gone brittle it no longer closes around the sheath, and condensation or driven rain finds its way in. Replacing a worn gland at the same time as a cable, a sensor or a control board is good practice, since the gland costs a fraction of the parts it protects.

Fitting and maintenance notes

Work on the dry side first: fit the body into the panel and secure it with the locknut before the cable is routed, so the housing is not twisted with a live lead inside it. Tighten the compression nut by hand until the insert visibly closes on the sheath, then a little further — overtightening can deform the insert and reduce the seal rather than improve it. Leave a short drip loop in the cable below the entry so water runs off instead of tracking along the sheath towards the gland. All electrical work on pool equipment should be carried out in line with local regulations and, where required, by a qualified electrician.

Here we list the Guagzhou Yinfu parts held in the catalogue, including the PG7 cable gland for 5 to 7 mm cables under article number PPS-10315. It is a straightforward replacement item for control boxes, transformer housings and junction boxes where the original gland has perished or gone missing.

Small sealing and cable-entry components are easy to overlook when ordering, yet they are exactly what holds up a repair when the rest of the parts have arrived. Searching by article number is the fastest way to confirm you have the right item; if you are matching an existing gland, measure the cable and the panel hole first and compare them with the figures above.
