Boly specializes in manufacturing high-performance sensor housing or industrial customers, delivering critical components for fluid, pressure, motion, position, vibration, force, and temperature control systems.
Our CNC-machined sensor components are crafted from durable materials such as Stainless Steel, Nickel Alloy, Brass, and Aluminum, offering fully customizable designs to meet exact specifications.
The primary functions of a sensor include:
Monitoring – The sensor provides information to a display or recording device.
Feedback – The information provided is based on a condition or changes in a phenomenon, which then controls the function to maintain parameters within a selected range.
Intelligence – By adding intelligence within systems, sensors help process data and enable complex autonomous decisions in operations.
From rugged stainless steel sensor housings for harsh environments to precision sensor fittings that ensure leak-proof connections, we proudly support OEMs and sensor manufacturers worldwide. Furthermore, our expertise extends to producing metal parts for gauges, transmitters, switches, data loggers, and monitors that rely on pressure sensor technology and mechanical systems.
The sensor industry demands products that meet exact specifications and the highest standards for reliability and quality. Through a combination of advanced technology and in-house engineering expertise, we specialize in designing, manufacturing, and delivering high-quality sensor housings, sensor fittings, and sub-assemblies tailored to meet diverse industrial needs. Our precision-engineered sensor housings and sensor fittings are widely used in applications such as measuring equipment, automotive testing, fluid control, hydraulic measurement, industrial process monitoring, and medical devices. At Boly, we provide OEM services to global industrial customers, adhering to international standards and ensuring exceptional performance for every product.

Nickel and High Temperature Alloys
Nickel steel alloys are extremely popular for sensor housings and fittings. It is designed for critical applications where extreme conditions are required. This demand is due to its increased hardness, tensile strength, and elastic limit, all without reduced ductility. It also maintains strength at elevated temperatures as high as 1,050˚C to 1,200˚C. The nickel-based super alloys Inconel and Hastelloy are also used extensively.
Below are some of the grades in stock:
Nickel-Chromium Alloys – Inconel®
Inconel 600
Inconel 617
Inconel 625
Inconel 718
Nickel-Molybdenum-Chromium Alloys – Hastelloy®
