FCST-15JDB-SC
Product Overview
A Straight Connector Built for Direct Burial. No Rust. No Leaks. No Rethink.
Underground microduct networks face a simple but costly reality: the weakest connection determines the lifespan of the entire link. Water ingress, corrosion, impact damage from backfill, or a failed seal—any of these can turn a routine splice into an expensive excavation.
FCST-15JDB-SC Microduct Straight Connector is a metal-free, push-fit microduct straight connector engineered specifically for direct burial (DB) and direct installation (DI) environments. It combines a crystal-clear, impact-resistant body with IP68-rated sealing and a pre-assembled safety locking clip—giving you a connection you can install quickly and forget for decades.
- Pre-assembled safety locking clip.
- Certified for 15 J impact resistance.
- Universal bore design reduces the number of connector variants customers need to stock and manage.
- Anti-sediment design; chemically resistant.
- All-plastic, metal-free design eliminates the risk of rust.
- For 7-16 mm microducts; OEM customization is available.
- Suitable for direct-burial (DB) applications.
- Easy push-in installation; crystal-clear transparent body.
- Components are made of recyclable materials to reduce CO2 emissions.
