Featuring two ferrules, a body with threaded ends, and a bulkhead nut arranged at a 90-degree angle, this fitting enables tubing to navigate corners or obstacles seamlessly. Bulkhead union elbows find widespread use in applications where space constraints necessitate precise routing of tubing through confined spaces or around complex geometries. Their robust construction and leak-proof design ensure optimal performance and system integrity in diverse industries such as telecommunications, transportation, and industrial automation.

Connector NPT:

A connector NPT (National Pipe Thread) is a specialized tube fitting incorporating threaded ends designed to interface with NPT threaded fittings or components. Featuring a ferrule and a body with NPT threads, this fitting ensures secure and sealed connections when tightened. Connector NPT fittings are indispensable in plumbing, pneumatic, and hydraulic systems utilizing NPT threaded connections, providing reliable interfaces for fluid or gas transfer. Their compatibility with standard NPT threads ensures seamless integration and dependable performance in various industrial applications.

Male Connector NPT:

A male connector NPT offers a robust solution for connecting tubes or pipes to female NPT threaded ports or components. Featuring external NPT threads on one end and a tube fitting connection on the other, this fitting ensures secure and leak-free interfaces in fluid or gas transfer systems. Male connector NPT fittings are indispensable in applications requiring reliable connections between tubing and NPT threaded systems, providing versatility and performance across industries such as construction, automotive, and HVAC.

Male Elbow NPT:

A male elbow NPT combines the functionality of an elbow fitting with external NPT threads, facilitating directional changes in tubing while accommodating NPT threaded connections. Featuring external NPT threads on one end and a tube fitting connection at a 90-degree angle on the other, this fitting enables seamless integration of tubing with NPT threaded ports or components. Male elbow NPT fittings find widespread use in applications where space constraints necessitate precise routing of tubing at right angles to NPT threaded connections, ensuring optimal flow dynamics and system efficiency.

Male Bulkhead Connector:

A male bulkhead connector is a specialized tube fitting engineered for seamless integration through panels or enclosures, providing leak-proof connections between tubing on either side of the panel.

What size round tubing fits inside each other?

Round tubing sizes can vary significantly depending on factors like material, wall thickness, and manufacturing standards. However, commonly available round tubing sizes are often designed to fit inside each other based on their outside diameter (OD) and inside diameter (ID) measurements. This nesting capability is particularly useful in applications where telescoping or sliding components are required, such as in furniture, machinery, or structural frameworks.

For instance, a tubing with an OD of 1 inch may have an ID slightly larger than another tubing with an OD of 0.75 inches, allowing the smaller tubing to fit snugly inside the larger one. The specific sizes that fit inside each other will depend on the tolerances and specifications provided by the manufacturer.

In engineering and manufacturing, engineers and designers typically refer to tubing sizes based on industry standards such as ASTM or ISO, which provide standardized dimensions and tolerances for tubing. By adhering to these standards, it becomes easier to predict and ensure proper fits between different sizes of round tubing, facilitating efficient assembly and construction processes.
