Why HVAC Matters for Precision Engineering
The Heating, Ventilation, and Air Conditioning (HVAC) industry is essential for maintaining climate control in homes, commercial buildings, industrial facilities, and transportation systems. As the demand for energy efficiency and reliability increases, so does the need for high-quality, precision-engineered components.
At Sheldon Precision, the HVAC market presents a valuable opportunity to supply precision turned parts that enhance the performance, durability, and innovation of HVAC systems.
What Are Turned Parts – And Why Do They Matter in HVAC?
Turned parts are precision components manufactured on lathes or CNC turning machines. In simple terms, they are typically used when a part requires a high degree of roundness, threading, grooving or contouring.
In HVAC systems, these parts are often essential for:
- Securing pipe fittings and valves
- Creating connections for sensors, filters and flow control devices
- Ensuring durable and corrosion-resistant joins in high-pressure systems
- Producing rotating or moving parts with consistent tolerances
Given that HVAC systems rely on continuous, uninterrupted airflow and fluid transfer, poorly manufactured or inconsistent parts can lead to leaks, system failures or reduced efficiency. Precision-turned components help avoid these risks.

Key HVAC Components That Use Turned Parts
The HVAC sector is built on a wide range of mechanical components, many of which depend on small but vital turned parts. Some of the most common include:
- Compressor and Pump Fittings
Air conditioning and refrigeration units often require tightly sealed fittings and connectors to prevent leaks. Turned parts ensure precise tolerances for fluid pathways, minimising leaks and supporting pressure regulation.
- Valve Bodies and Spindles
Control valves regulate temperature, pressure, and airflow. Turned valve spindles and seats provide durability and accuracy in high-cycle environments.
- Thermostat and Sensor Casings
Protective housings for sensors and thermostatic controls require high-accuracy machining to ensure seamless integration with electrical and thermal components.
- Custom Fasteners and Connectors
HVAC installation and maintenance often depend on custom-sized fasteners, many of which are manufactured as turned parts for strength and repeatability.
- Flow Control Components
Orifice fittings, restrictors and nozzles used to manage air and fluid flow often require CNC turning to achieve the exact bore size and finish.

Materials Matter: Metals Commonly Used in HVAC Turned Parts
The materials used for turned components in HVAC must withstand heat, moisture, pressure and sometimes corrosive substances. Common choices include:
- Aluminium – lightweight and thermally conductive
- Brass – corrosion-resistant, ideal for fittings
- Mild Steel – economical and strong for general parts
- Stainless Steel – durable and heat-resistant
We work with all these materials at Sheldon Precision, customising our approach to each component’s end-use.
