FCST-GASE Gas & Water Block Microduct End Caps are designed to provide dependable sealing for HDPE microduct systems used in modern FTTx deployments. Suitable for both empty ducts and microducts carrying fiber cables, they effectively prevent the ingress of water, gas, dust, and other contaminants at critical network termination points.
Common installation locations include fiber distribution cabinets, splice closures, ODFs, handholes, and customer termination points. Their transparent body allows installers to visually confirm cable positioning without disassembly, while the push-fit design enables fast installation without special tools.
Reliable Gas & Water Sealing
Engineered to provide gas- and water-tight sealing up to 0.5 bar, helping maintain network integrity in demanding outdoor environments.
Built for High-Pressure Networks
Designed for a 20 bar working pressure with a 25 bar burst pressure, making them suitable for air-blown fiber installations and high-pressure microduct systems.
Ready for Underground Deployment
Constructed for both direct buried (DB) and above-ground applications, delivering long-term performance under varying environmental conditions.
Tool-Free Installation
The push-fit locking mechanism allows quick installation and removal while ensuring secure cable retention.
Long Service Life
Manufactured from UV-resistant engineering plastics with corrosion-resistant components for an expected service life of 25 years under normal operating conditions.
Transparent Body: Polycarbonate (PC) for excellent impact resistance and visual inspection.
Sealing Components: High-quality EPDM and silicone rubber to ensure stable sealing across a wide temperature range.
Mechanical Parts: Precision-molded POM release sleeve, locking nut and locking clip, combined with a stainless steel circlip for dependable mechanical performance.
Each FCST-GSAE End Cap is engineered and tested to meet demanding telecom installation requirements.
