Engineered here, not sourced
Original R&D since 1974, a DSIR-recognised centre, and a plant that runs 24×7 behind it.
DSIR-recognised R&D centre
Recognised as an In-House R&D Centre by the Department of Scientific & Industrial Research, Government of India. 10,500 sq ft at Chakan, Pune.
Two patent granted, more filed
Several further disclosures filed. The DIN progressive ring's hardened cutting edge is produced by a proprietary patented process.
25+ new products in recent years
Developed for customers on a Design for Six Sigma platform — design, FEA, prototyping, then testing, with in-house or third-party certification on request.
Published original research
FC's own research appears in national and international technical journals — not a claim most connector suppliers can make.
Indigenous replacements for imports
An ethos since 1974: developing Indian-made replacements for imported parts. The Make-in-India route for a programme with a localisation target.
Full analysis toolchain, in house
SolidWorks, ANSYS, AutoCAD, HyperMesh and PDMS. FEA covers vibration impact, reliability, life estimation and energy absorption of connectors.
The plant behind the order
- Chakan, Pune — 120,000 sq ft site, 60,000 sq ft covered
- Production and assembly running 24×7
- Precision parts on automated equipment and multi-spindle CNCs
- 5-axis CNC tube bending; every bend checked on a CMM
- Hose cutting, skiving, crimping and nut crimping in house
- Dedicated equipment for tube and hose assemblies
Designs that started here
Developed by Fluid Controls for rolling stock problems a standard catalogue part does not solve.
Across Frame Connector
Designed by FC for electric locomotives: a swivelling bulkhead adaptor joining brake pipelines across the bogie-to-shell panel, eliminating welding operations and the time and cost with them.
Latched isolating cock
A locomotive underframe ball valve whose handle latches in position, so a brake circuit cannot be opened inadvertently in service.
FlexiGrip connector
Triple sealing — split ring, washer and O-ring — for zero-leak joints on pipes mis-aligned up to three inches or made of different materials, with make-and-break re-usability.
Patented progressive ring
The cutting edge of the DIN single ferrule ring is case-hardened by a proprietary patented process; single- and double-bite variants for higher pressures and high-vibration environments.
What we can prove
Rail qualification testing in our own NABL ISO/IEC 17025-accredited laboratory at Chakan, Pune — no third-party queue between a design change and its evidence.
