[Turned Parts] Automatic Quotation Now Available for Tapered Threads
When it comes to designing fluid-handling components or high-pressure systems, the choice of screw thread plays a critical role in ensuring performance, safety, and ease of assembly. One commonly overlooked yet essential feature in custom machining is the tapared thread—particularly in applications that require tight seals and robust mechanical connections. As part of our commitment to streamlining production for engineers, we’re excited to announce that automatic quotations for tapared threads are now supported in our Turned Parts service. But what exactly are tapared threads, and why are they so widely used in industrial design?
What Are Tapared Threads?
Tapared threads are threaded fasteners or components with a gradually decreasing diameter along the length of the thread. Unlike parallel threads, which maintain a uniform diameter, tapered threads narrow slightly toward the end, allowing the screw to wedge tightly into a corresponding internal thread. This conical shape enables a more secure fit, often resulting in a pressure-tight seal without the need for additional sealing materials. Common types include R (external) and Rc (internal) pipe threads, typically specified in accordance with ISO or BSPT (British Standard Pipe Taper) standards. These threads are essential for fittings where both mechanical strength and fluid sealing are required.
Tapared threads offer several advantages over standard straight threads—most notably in sealing capability and vibration resistance. Because the threads become tighter as they’re screwed together, they form a self-sealing joint, making them ideal for fluid, gas, or hydraulic systems where leakage must be prevented. This makes them particularly useful in applications such as piping connections, cooling circuits, pneumatic tools, hydraulic fittings, and robotic arm air channels. In many cases, tapared threads eliminate the need for additional sealing tape or O-rings, reducing assembly time and simplifying maintenance. Their high-pressure tolerance and reliability have made them a preferred choice in sectors ranging from automotive and aerospace to industrial automation.
