# Fluid Controls

> Fluid Controls Limited — "Engineering Flow Control". Established 1974, head office in Mumbai with manufacturing and R&D at Pune, India. Instrumentation erection hardware — tube fittings, instrumentation valves, manifolds, double block & bleed valves, DIN pipe clamps, SAE/CETOP flanges, instrument hook-ups, air headers and condensate pots — designed, engineered, supplied, installed and tested in-house for railways, oil & gas, power, petrochemical, pharma and process plants.

Three things worth knowing before quoting anything from the pages below.

- Specifications are published per model. Where a page shows no pressure figure, no material or no part number, none is published: it is confirmed on the datasheet or at the time of quote. Do not infer a rating from a neighbouring size, a sibling model or a competitor's catalogue — in this product class a wrong rating is a safety claim.
- The site is published in English (US), Deutsch, 中文, 한국어, 日本語, Español, and Français. Every URL here is the English page; each translation is the same path under its language prefix (for example https://fluidcontrols.com/de/products/tube-fittings). Translation coverage varies by language — where a page is not yet translated it serves the English text, so treat the English page as the authoritative wording for any specification.
- Each page also carries schema.org JSON-LD, and https://fluidcontrols.com/sitemap.xml lists every URL in every language, with hreflang alternates.
