SS 304 Stub End Fittings Available in Following Metals & Grades

Stainless Steel 304

Our SS 304 Stub End Fittings are butt-weld components used in conjunction with Lap Joint Flanges to create a versatile piping connection. The stub end is welded to the pipe, while the flange acts as a loose backing ring that slides over it. As a leading SS 304 Stub End Fittings Manufacturer in Mumbai and Maharashtra, we produce both Short Pattern (MSS SP-43) and Long Pattern (ASA) types. Manufactured from high-quality Stainless Steel 304, these fittings offer excellent corrosion resistance and cost savings, as only the stub end contacts the fluid, allowing the backing flange to be made of a cheaper material like carbon steel. Choose us as your reliable SS 304 Stub End Fittings Supplier in India.

Benefits and Application of SS 304 Stub End Fittings

Reduced Material Costs: Since only the stub end needs to be made of corrosion-resistant SS 304, the backing flange can be made of lower-cost carbon steel, significantly reducing total project costs.

Easy Flange Alignment: The backing flange rotates freely around the stub end, allowing for easy alignment of bolt holes with the mating flange, eliminating installation struggles.

Versatile Maintenance: The loose flange design allows for quick disassembly and maintenance of the joint without needing to cut or re-weld the pipe, saving downtime.

Some FAQ


What is the main purpose of a Stub End?	A stub end creates a flanged connection where the flange itself is not welded to the pipe but sits loosely behind the stub, allowing for easy rotation and alignment.
Are you an SS 304 Stub End Fittings Supplier in Mumbai?	Yes, we are a Mumbai-based supplier with a comprehensive inventory of stub ends to meet the needs of industries across Maharashtra and India.
What is the difference between Short and Long pattern Stub Ends?	Short pattern stub ends have a shorter overall length and are typically used with lower pressure flanges, while Long pattern stub ends are longer to accommodate larger backing flanges.
Can SS 304 Stub Ends be used with Carbon Steel flanges?	Yes, this is the most common application. The SS 304 stub end handles the fluid contact, while the cheaper Carbon Steel flange provides the bolting pressure.
Do you provide Mill Test Certificates?	Yes, we provide Mill Test Certificates (MTC) as per EN 10204 3.1 with every order to verify the chemical and mechanical properties of the stainless steel.
Is welding required for a Stub End?	Yes, the stub end itself is butt-welded to the pipe. The lap joint flange is slipped over the stub end before welding.
What standards do your stub ends meet?	Our stub ends are manufactured to ANSI/ASME B16.9 and MSS SP-43 dimensions, ensuring compatibility with standard pipe sizes and lap joint flanges.
Can these fittings be used for high-pressure applications?	Yes, when used with appropriate high-pressure backing flanges and welded correctly, stub ends are suitable for many industrial pressure ratings.
