OM Tubes is a principal manufacturer and supplier of fine quality tube fittings.Tube fittings are also popularly known as compression fittings, ferrule fittings, and instrumentation fittings. Tube fittings are manufactured in various grades of Stainless Steel & Nickel Alloys. We manufacture all types of fittings to your personal requirements, but the most common types of tube fittings that we manufacture include elbow fittings, connectors, adapters, expansion joint coupling fittings, push-in, nipple, plug, gland, and bulkhead fittings, among a vast number of others. The most basic specifications and modifications that we consider in the preliminary stages of designing tube fittings include material type, tube size, and port size. Our Tube fittings are available in numerous configurations and sizes. We are the most comprehensive addition to the industry that offers a complete portfolio of products associated with tube fittings. Our Production Capacity has up to 25000 units per month and our Fittings strong endurance and durability, with precision in Threading (NPT, BSPT, BSPP). Each and every individual unit is tested to gauge and pressure before it leaves the premisesPlease feel free to request samples for regular size and requirements.


Tube Fittings is a product that is used to provide a leak free connection between tubes for a seamless flow of liquids and gases. Tube fittings are manufactured to meet even the most volatile and rigorous specifications required by industries and are most commonly used in the oil and gas, pulp & paper, petrochemical/chemical processing, research laboratories, aerospace and defense, chemical processing, power generation, cryogenic and semiconductor, shipbuilding and heavy industrial industries.The most Common types of tube fittings manufactured by us are nickel- and chrome-plated fittings which are used for their corrosion resistance or to provide aesthetic finishes.

It is important to know which fittings should be used in which application. The first step to determining the type of fitting right for the application is to establish the basic system type. The three common applications are:

  • Hydraulic applications: They involve the transfer of liquid fluids such as water and other chemical solvents. Hydraulic fittings must have seals which prevent the leakage of liquid and often be resistant to rust or other possible chemical corrosion.
  • Pneumatic applications: They involve the transfer of gases. Pneumatic fittings must have very tight seals to prevent gas leakage and must be resistant to chemical corrosion.
  • Other applications: They are applications such as structural design, which also incorporate tube fittings. These fittings must have strong physical integrity, but typically do not require sealing because they do not carry fluids.

Tube fittings are available in a number of sizes and configurations. They range from sizes 1/16” to 2” with a number of choices in connections and end patterns. Tube fittings  are normally measured by inside diameter (ID), outer diameter (OD), wall thickness and material hardness. Tube fittings are made up of the 4 vital parts, namely: A body, a front ferrule, a back ferrule, and a nut. There are also a number of grades of tube fittings and connections available.

Our state of the art factory has 21 CNC Machines, 12 Lathe Machines, 3 Heavy Punch Machines, and 5 Dye Machines for an end to end process at one place. Our production capacity at peak in a 3 shift schedule is 1.3 million pieces of assembled units per month. Added to that we have in house testing facilities like Spectro machine, PMI Machine, Mechanical Test, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing, and manual inspection of gauge. Our product range also includes instrumentation valves, condensate pots, snubber, manifolds, and custom designed valves. Tube Fittings can be made in NPT, BSPT & BSPP Threads.

The production process can be divided for BODY, NUTS and FERRULES :

  • Body:As per design standard the body is made from hex or round bar which is subject to heat treatment depending on the stature of the bar. Followed by that, the body is machined depending on the thread required by customer.
  • Nuts:Nuts are made in a fairly simple process by a machining of hex bar as per size and thread for a standardized design.
  • Ferrule: Ferrules are the heart of the tube fittings. Our specialization lies in the manufacture of an innovative method that makes the ferrules compatible with other manufacturer designs and increases the life of the fitting.


As a Tube Fittings, OM Tubes is backed by all the possible certifications of a world class mill, including ISO 9001:2008, ISO 14001:2007, OHSAS 18001: 2004 & CE-PED 97/23/EC. We are also members of various renowned agencies and Chambers of Commerce including MASSMA, EEPC, FICCI, FIEO, Indian Merchants Chamber etc.. Coupled with that i-LOK tube fittings are supplied with a default one year product replacement warranty against customer word without any further questions. We are confident because 100% tube fittings are tested in house for any defects in quality or manufacturing workmanship. Not even a single fitting can leave the premises without a 3 layer inspection of chemical test, mechanical test, visual inspection, dimension inspection, pressure test, gauge test and conformity to the order. Thus we are generally stuffed with loads of orders for 90 day schedule ahead of time.Each heat and lot of tube fittings are supplied with a material test certificate as per EN 10204 NACE 3.1 standards indicating the chemical and mechanical properties of the fittings along with pressure rating. We also confirm the guarantee of the fittings supplied as per Purchase order specifications and attest the same in the Material Test Certificate. We also welcome any third party inspection from an agency nominated by the customer to comply with NACE 3.2 Certification if required by customer at an extra cost.
