Internal Swivel Tee Structural Pipe Fittings are widely used in handrail, guardrail, and other modular structures. Their unique design allows connected fittings to rotate freely around the joint, offering more flexibility in installation. This makes them especially suitable for angled or inclined systems where adjustments are necessary. HULK Metal provides these fittings in multiple materials, finishes, and sizes to match different project demands and ensure higher performance.
Originally designed to create connection points on the uprights of handrail and guardrail systems, the Internal Swivel Tee Structural Pipe Fitting allows additional fittings to rotate 360 deg around the joint. This feature makes it ideal for angled structures or systems requiring flexible alignment while maintaining stability and strength.
Its sleeve fits over any position on the pipe, secured firmly with an internal hex set screw. The plug is designed to insert into the socket of another fitting, enabling the connected fitting to rotate around the joint. This simple but strong structure makes the Internal Swivel Tee versatile in use.
The Internal Swivel Tee provides adjustable and secure connections in complex structures. Its ability to rotate makes installation easier and reduces the need for additional cutting or welding. It supports various surface treatments to enhance corrosion resistance, ensuring it lasts longer in outdoor environments. The fitting combines flexibility, strength, and convenience.
When you need to add a point to a pipe that can also connect other structural pipe fittings, the Internal Swivel Tee is a practical choice.
In guardrail and handrail systems, it allows uprights to adjust at any angle, especially in sloped areas.
It can provide a sleeve for connecting top rails at different angles.
In DIY structures, it offers even broader applications, from modular frameworks to customized furniture, supporting more creative designs with strong, adjustable joints.
The sleeve fits onto the pipe and is tightened with a hex bolt. The plug connects to another fitting socket, allowing free 360 deg rotation around the point.
HULK Metal produces Internal Swivel Tee fittings in cast iron, stainless steel, and aluminum to suit different environments.
Available in malleable iron and ductile iron, cast iron fittings offer excellent strength and cost-effectiveness. They are ideal for heavy-duty structures where durability is essential. Ductile iron provides added flexibility compared to malleable iron, making the fitting stronger and more impact-resistant while maintaining a stable and reliable performance.
Stainless steel Internal Swivel Tee fittings offer superior corrosion resistance and a modern appearance. They are suitable for environments exposed to moisture or chemicals, such as marine, industrial, or architectural projects. Their clean finish makes them an excellent option for structures where aesthetics is as important as strength.
Aluminum fittings are lightweight yet durable, offering good corrosion resistance. They are perfect for projects requiring easier handling or where weight is a concern. Aluminum's natural resistance to oxidation ensures the fittings stay reliable in outdoor conditions, while still delivering strong structural performance for modular construction.
Different finishes increase corrosion resistance and improve appearance, making Internal Swivel Tee fittings suitable for varied environments.
Hot-dip galvanizing forms a thick zinc coating that provides excellent corrosion resistance, especially in outdoor and industrial applications. This process ensures the fitting can withstand harsh weather, moisture, and heavy use. It is widely chosen for structural projects that require stronger durability and longer service life in demanding environments.
Double-coating galvanizing combines hot-dip and electro-galvanizing to achieve enhanced corrosion resistance. The first layer ensures deep zinc penetration, while the second creates a smoother finish. This process improves overall durability, adds extra protection in coastal or humid conditions, and extends the fitting's service life beyond that of standard galvanizing treatments.
Powder coating offers both protective and decorative finishes. The coating creates a strong, uniform layer resistant to scratches, impacts, and UV exposure. It is available in customizable colors, making fittings not only corrosion-resistant but also visually appealing. Powder coating is particularly suitable for architectural projects and customized modular structures.
This fitting cannot directly connect two pipes but must work with other fittings.
For direct pipe-to-pipe connections, a single socket tee is recommended.
Confirm whether the fitting size matches the system requirements.
Ensure the surface treatment is suitable for the application environment.
Check compliance with local installation standards.
A reliable supplier should strictly follow ISO 9001 quality standards and provide certifications. This ensures the Internal Swivel Tee fittings meet structural performance requirements. A strong quality assurance system guarantees that every fitting is tested before shipment, reducing risks for your project and helping you avoid costly replacements.
When choosing a supplier, assess whether they can handle bulk orders without compromising quality. Factories with advanced casting, machining, and finishing equipment can deliver higher precision and faster turnaround. A strong production capacity also means stable supply, fewer delays, and a better chance of meeting tight project schedules.
Projects often require non-standard fittings or special finishes. A good supplier should support customizable materials, dimensions, and coatings. This flexibility helps you get fittings that better match your project needs. It also ensures compatibility with other parts of your system, creating smoother installations and stronger structural performance.
Suppliers with reliable after-sales services help you avoid long-term risks. Comprehensive support includes warranty, return, and exchange policies. They should also offer professional guidance for installation and surface treatment maintenance. Strong after-sales support ensures long-term reliability and provides buyers with more confidence when purchasing Internal Swivel Tee fittings.

Raw materials are sourced from reliable suppliers and undergo strict testing for strength and consistency. Every batch of malleable iron or ductile iron is inspected in our QC center to ensure compliance with ISO standards before entering the production process.
We strictly follow ISO9001-certified procedures throughout production. Casting, machining, and surface treatment are carefully controlled to maintain consistency. Each step includes inspections to ensure the Internal Swivel Tee fittings meet higher standards for strength, durability, and appearance before moving forward in production.
The casting process uses precision molds to form fittings with consistent dimensions. Malleable iron or ductile iron is melted, poured, and cooled under controlled conditions. This ensures uniform density, reduces defects, and creates strong, reliable Internal Swivel Tee parts ready for further finishing.
After casting, each part undergoes machining and finishing processes to remove burrs, smooth edges, and ensure precise measurements. These steps improve overall quality, enhance assembly fit, and prepare the fittings for surface treatment. Finishing ensures durability and a better appearance.
Dimensional checks, visual inspections, and strength tests are performed at this stage. Each fitting is compared with technical standards to confirm it meets size, structure, and performance requirements. Defective parts are removed, ensuring only qualified Internal Swivel Tee fittings continue for surface treatment.
Fittings undergo galvanizing or powder coating, depending on customer requirements. This process provides corrosion resistance and a clean finish. Our surface treatment methods ensure coatings are thicker, more uniform, and more wear-resistant, enhancing durability for outdoor or heavy-duty applications.
Another round of inspections follows surface treatment. Coating thickness, adhesion, and overall appearance are tested. Only fittings that pass these checks are approved for packaging. This guarantees the final Internal Swivel Tee products meet high standards for performance and durability.
Products are carefully packaged to prevent damage during transit. We offer customizable packaging, including cartons, wooden cases, or pallets.
