Solid Electrical’s long-standing presence in the market and global reach speak to the trust they have built through consistent product performance and customer service.
Installing the 25mm plain-to-female conduit adapter is straightforward. First, ensure the power is turned off to any circuits you’ll be working on. Measure and cut your 25 mm PVC conduit to the desired length, making sure the cut is clean and square. Apply a coat of PVC solvent cement to the outside of the conduit’s plain end and the inside of the adapter’s plain socket. Immediately push the adapter onto the conduit end with a slight twist – this ensures a good bond. Hold it in place for a few seconds while the cement sets.
On the threaded female end of the adapter, you can now screw it onto the corresponding male threaded fitting. For example, if you’re attaching the conduit to a junction box with a male threaded outlet, insert the male end into the adapter and tighten by hand, then give it a snug further turn if necessary (using channel locks or a wrench gently, as the fitting is PVC). No special tools are required beyond a saw for cutting conduit and the PVC glue.
Once installed, the adapter provides a secure, conduit fitting connection – the plain end is permanently glued, and the other end is firmly screwed in, creating a continuous protective path for your wiring.
Always let the solvent cement fully cure as per the glue manufacturer’s instructions before pulling cables through the conduit, and abide by local electrical codes (if unsure, consult a licensed electrician).
Yes. The adapter is designed according to standard 25 mm conduit thread specifications, so it will fit any common electrical conduit accessories that have a matching 25 mm male thread. For instance, you can screw it onto the threaded spout of an electrical junction box, an enclosure knockout fitted with a male threaded bush, or a 25 mm conduit gland. This universal compatibility means you aren’t limited to one brand’s system – the plain to female adapter will interface with other standard PVC conduit components on the market.
Whether you’re connecting to a junction box, an elbow, or a piece of equipment with a threaded entry, the adapter serves as the link between your plain PVC conduit and that threaded connection.
Just remember that the plain side of the adapter only mates with 25 mm plain conduit (it glues inside a 25 mm conduit pipe), and the female threaded side will accept any 25 mm size male thread. This makes it a versatile component in any conduit installation, allowing different pieces of your electrical system to connect seamlessly.
Absolutely. This conduit fitting is made from rigid PVC that is formulated to be UV-resistant, so it won’t crack or degrade quickly even with prolonged exposure to sunlight. That makes it well-suited for outdoor use, such as on rooftops or exterior walls – a key consideration for solar photovoltaic installations or outdoor security lighting. In terms of fire safety, the PVC material is self-extinguishing (fire resistant). It will not support combustion, meaning if there’s a flame, the material will tend to extinguish itself rather than burn freely.
This fire-retardant property is important for maintaining safety in electrical installations. Additionally, the adapter can handle typical outdoor temperature ranges and is moisture-resistant. If it’s used in a wet location, you should pair it with appropriate waterproof conduit seals or boxes to ensure no water ingress at the connection point (the adapter itself doesn’t have a gasket, so sealing tape or a rated enclosure might be needed for a fully watertight setup).
Overall, it’s built to perform in both indoor and outdoor environments while safeguarding your wiring against UV rays and fire hazards.
Yes, the plain to female conduit adapter is usually available in at least one other common size: 20 mm diameter, which is used for smaller conduit runs. The 20 mm plain-to-female adapter functions exactly the same way as the 25 mm version – allowing you to connect 20 mm plain conduit to a threaded fitting – just scaled down for the smaller conduit.
Both the 20 mm and 25 mm adapters share the same design features (PVC material, threaded end, etc.) and both comply with the relevant standards. They also come packaged in similar quantities (for instance, 1000 pcs per carton) for bulk supply. In addition to size variants, the manufacturer offers a range of complementary conduit accessories and adapters (such as plain-to-plain couplers, male bushes, and angle fittings) to cover different installation needs.
Always choose the adapter size that matches your conduit diameter; using the correct size ensures a tight fit and maintains the integrity of the conduit system.
The plain to female adapter is intended for one-time installation, particularly on the glued side. Once you glue the plain end into a PVC conduit, that joint is permanent – the solvent welding process actually fuses the plastic together. Trying to remove a glued adapter would likely require cutting the conduit.
The threaded connection on the other side, however, is removable. You can unscrew the adapter from the mating male thread if you need to disconnect that end (for example, unscrewing it from a junction box or equipment during maintenance or re-routing). Keep in mind, though, that the female adapter itself may have some cured PVC glue residue on the plain end once removed, making it impractical to reuse on a new conduit.
In general, it’s best to consider the adapter as a semi-permanent component: you can detach the threaded side for equipment servicing or rewiring, but the adapter will remain attached to the original conduit unless cut off. Plan your conduit runs carefully before gluing, and use a new adapter if you need to reroute or change your conduit layout later.
Yes, this adapter is commonly used in solar photovoltaic (PV) installations to ensure safe and neat wiring. In a rooftop solar setup, for example, you might run DC cables from the solar panels through 25 mm conduit, and at the point where these conduits enter a combiner box or an inverter, you’ll use a plain-to-female adapter.
The plain end attaches to the conduit coming from the roof, and the female threaded end screws onto a male thread of the PV combiner box or inverter housing. This keeps the cable entry watertight (when used with appropriate gaskets or cable glands) and mechanically secure.
The adapter’s UV-resistant PVC and secure threading are beneficial here – they can withstand the intense sun exposure on the roof and remain firmly in place even if there’s vibration or movement (for instance, due to wind or thermal expansion). Using proper conduit fittings like this adapter in solar installations helps protect the cables from weather and physical damage, reducing the risk of electrical faults.
Always ensure that all conduit components in a solar project are appropriately rated for outdoor use and are installed according to electrical codes and the solar equipment manufacturer’s guidelines.
