Youeon 2.5" 45° Mandrel Bend Elbow Pipe Fittings — 304 Stainless Steel, 16GA Pack of 6

This pack contains six precision-formed 45-degree elbows with an outer diameter of 2.5 inches (63 mm) and a wall thickness of 16GA (approximately 0.06 in / 1.5 mm). Each elbow is mandrel-bent from 304 stainless steel for consistent shape and improved flow or aesthetic continuity. The parts arrive with a polished surface and burr-free edges for faster preparation and professional-looking joins.

How do these elbows fit into exhaust or piping projects?

These elbows offer a clean, repeatable bend at a 45° angle that matches many aftermarket exhaust and custom piping layouts. The mandrel bend preserves the tube profile for better internal flow and easier alignment when fabricating or replacing sections.

• Outer diameter: 2.5 in (63 mm) to match common tubing sizes
• Wall thickness: 16GA / 0.06 in / 1.5 mm for good stiffness
• Mandrel-formed cross-section for minimal deformation
• Pack of six for multi-piece assemblies or spares

Will these elbows resist rust and last outdoors?

Constructed from 304 stainless steel, the elbows are inherently corrosion-resistant in many environments, making them suitable for exposed installations such as stair railings or outdoor ductwork. While 304 handles most atmospheres well, you should consider local conditions like salt spray when choosing materials.

• Material: 304 stainless steel for general corrosion resistance
• Polished finish slows surface oxidation and eases cleaning
• Recommended for non-marine and mild outdoor environments
• Compatible with standard stainless welding and finishing techniques

How easy are these elbows to cut, weld, and install?

The elbows are supplied with smooth, deburred edges and a polished exterior, which reduces prep time prior to welding or joining. They work with common metalworking tools and joinery methods—cleaning pipe ends before assembly improves fit and final weld quality.

• Burr-free cuts speed up fitment and alignment
• Suitable for TIG, MIG, and tack-welding after proper cleaning
• Trim with standard tube cutters or angle grinders if modification is needed
• Polished exterior eases finishing and final appearance work

What dimensions and quantity are included, and what should I check before buying?

This listing includes six elbows, each with a 2.5-inch outer diameter and a 45° bend. Verify your system's outer diameter, wall thickness tolerance, and intended joining method prior to purchase to ensure compatibility with existing tubing and fittings.

• Quantity: 6 pieces per set
• Outer diameter: 2.5 in / 63 mm
• Wall thickness: 16GA / 0.06 in / 1.5 mm
• Check mating tube OD and welding requirements before installation

Who is this for: These YOUEON elbows are aimed at fabricators, hobbyists, and installers who need reliable 45° stainless transitions for custom exhausts, handrails, or ornamental metalwork. If you require consistent bends, corrosion resistance, and quick prep for welding or assembly, this six-pack offers a practical balance of size, strength, and finish. For installations in very aggressive environments (coastal or chemical exposure), consider alternative alloys or protective coatings.
