Home improvement fittings designed to adapt larger threaded conduits to smaller ones with a secure, corrosion-resistant nylon connection, sourcing map Threaded Reducing Bushings. They keep runs neat and watertight, making electrical and DIY plumbing tasks less fiddly for installers and keen DIYers. Will three nylon bushings deliver reliable, repeatable joins on site?
⚡ At a Glance
- • Fitting Accuracy: Threads match M25 male and M20 female dimensions for a snug connection
- • Best for: Electricians, installers and DIYers adapting conduit or gland sizes on site
- • Not ideal for: Applications requiring metal-to-metal seals or high-temperature exposure
Three black nylon bushings adapt an M25 male thread to an M20 female thread. Durable, corrosion-resistant nylon construction suits general conduit and gland adaptation.
Secure, wobble-free joins - thanks to precise M25-to-M20 threading
Outer thread diameter is 24.8mm with an outer thread length of 9mm, while the inner thread diameter measures 20mm with an inner thread length of 13mm. Thread geometry creates a close mechanical fit between the male and female connections.
Consistent, snug fit reduces movement and helps prevent loosening during installation and everyday use.
Corrosion-resistant connections - with durable nylon construction
Made of nylon material described as durable and offering good corrosion resistance. The synthetic construction resists rust and many common environmental effects that affect metal fittings.
Suitable for damp locations and situations where metal adaptors would require more frequent replacement or treatment.
Ready for small-scale jobs - with a three-piece pack for multiple fixes
Package content includes 3 identical threaded bushings in black finish, allowing several installations or spares in one pack. Simple male-to-female threads mean no special tools are required beyond standard hand tools.
Keeps a small stock of adaptors on site for quick retrofits and routine maintenance without needing immediate reordering.
✨ The 4 Key Reasons for sourcing map Threaded Reducing Bushings
