Tech Tubes and Fittings is a leading manufacturer, trader and exporter of SS-ferrule-fittings which are referred to as ferrule fittings in chrome steel of grades 304 and 316. On the customer demand, these ferrule fittings available in other grades like brass, copper, titanium and other metals. Double ferrule fittings offer strong leak-proof connection in process, power and instrumentation process and are compressed into the assorted tubing, and need no flaring of the metal to put in. the only and double ferrule fittings are available in broad range of dimensions, materials, and configurations.

The single and double ferrule fittings are manufactured in India in a broad range of sizes, materials, and configurations. Stainless steel ferrule fittings are widely used in hydraulic and pneumatic applications in a range of industries such as oil and gas, petrochemicals, natural gas, fertilizers and power generation.

Double Ferrule Fittings are Manufacture and consists of 4 pieces. This parts are of the stainless-steel Double Ferrule Fittings include the Nut, the rear Ferrule, the Front Ferrule in addition because the Body. Upon installation, chrome steel Hose Ferrules becomes a five-piece connection. Once the tube has been attached to the chrome steel Double Ferrule Compression Fittings, they supply a solid leak free joint. Stainless-steel Double Ferrule Fittings are used across multiple industries like the pulp & paper, laboratories, downstream petrochemical, aeronautical and shipbuilding furthermore because the defence industry.

A steel Single Ferrule Compression Fittings will be attached by deforming it. Once the fitting is deformed, the steel Ferrule compressed and clamped round the tube. Performing this action on the Stainless Double Ferrule Fittings creates a fully tight seal. Which is why the chrome steel Ferrules is ready to resist the nominal pressure of the tubing. Jointly of the leading chrome steel Ferrule Fittings manufacturers in India, we provide various alloy grades and fairly priced fittings.

The Double Ferrule fittings and accessories are manufactured for fluid application in India. There are three components of Double Ferrule Fittings designed to provide a solid, secure, leak-free joint upon proper assembly. Double ferrule fittings are perfectly suited to tubes of steel, copper, or chrome steel where it's out of the question or permissible to braze, solder, weld, flare, or string. For tough application environments that need a minimized risk of leak paths and injury, single ferrule fittings are a wonderful option. Metals expand and consent temperature cycling systems, which creates dimensional adjustments for fitting connections. A "spring-loaded" effect that gives constant friction between the fitting body and also the nut is provided by double ferrule designs.

These double ferrule fittings are available many varieties like instrumentation tube fittings, compression tube fittings, hydraulic tube fittings, single, double, and double ferrule tube fittings and are customized as per client’s demand.


Double Ferrule fittings standard configuration Tube sizes vary from 1/16 to 2 outer diameter and 2mm to 50 mm OD. The fabric grades are available in S3 504, S5 316, brass and a few special alloys and have thread NPT, BSP, BSPT, and UNF. These tubes have various pressure ratings like 6000PSI for stainless-steel and 300/1000/30000 PSI for brass alloy. The Configuration of the tube has varied from tube to tubes like straight, elbow, tee, cross and bulkhead.


These double ferrule-fittings are widely utilized in hydraulic and pneumatic applications in an exceedingly various range of industries like oil and gas refineries, petrochemicals, fossil fuel, fertilizers, power generation and plenty of more. These stainless-steel ferrule tubes are exported to India moreover as in other countries.
