About
About Tube Fittings
Tube fittings for instrumentation, hydraulic and process tubing connections. Nascent supplies compression, bite-type and related tube fittings in stainless steel and compatible alloys for leak-tight joints under vibration and pressure cycling.
Available in elbows, tees, unions, connectors and adapters sized to common tube OD standards, with material certificates for oil & gas, chemical and utility systems.
Manufacturing note
Nascent fittings is a recognized manufacturer and supplier of Fitting End Closure, which are not designed for service in wet corrosive environments. The Fitting End Closure is the low carbon version of the alloy, and is operated for ease of fabrication. Super Duplex Steel Fitting End Closure are prone to intergranular corrosion after long term exposure at high temperatures. Tube Plugs (Fitting End Closures) are available in a variety of sizes and shapes with a variety of components. However, due to its high chromium content, these Fitting End Closure is more corrosion resistant than most heat resistant alloys. Monel Alloy Fitting End Closure has a carbon content restricted to exclude the lower end, so is the grade of choice for high temperature applications. The high chromium content of Hastelloy Alloy Fitting End Closure intends to increase high temperature properties and gives good aqueous corrosion resistance. Nascent fittings are equipped with cutting-edge technology and an expert workforce to ensure that work is enhanced.
Typical applications
