The 2200 system replaces traditional pneumatic indicators, eliminating the need for air lines and reducing maintenance complexity, while offering a simple calibration interface to facilitate setup and ongoing adjustments.

Hex Reducing Nipples Male NPT are pipe fittings designed to connect two female-threaded pipes of different diameters while maintaining a secure and leak-resistant seal. The male tapered threads provide a tight connection that prevents fluid leakage, which is especially important in high-pressure systems.

These fittings are widely used in the oil and gas industry, chemical processing, and instrumentation applications where a reduction in pipe size is required without adding extra joints.

They are manufactured from high-quality materials such as stainless steel, brass, and other compatible alloys, ensuring durability and resistance to corrosion. The fittings are precision-machined from bar stock to provide burr-free internal surfaces for smooth flow and to reduce turbulence within the system. Threads are carefully capped and packed to prevent damage during transit.

Hex Reducing Nipples are rated for pressures up to 10,000 PSI and comply with ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228 standards. They are designed for reliable performance in ambient temperatures from -28 to 37°C (-20 to 100°F) and support efficient installation with standard wrenches thanks to the hex shape, which allows secure tightening. These features make them suitable for high-pressure and instrumentation piping systems where both reliability and traceability are required.

The Monoflange DBB Double Block and Bleed Valve with Needle-Needle-Needle configuration is designed to provide dual isolation and safe venting in oil and gas, chemical, and process systems. Both isolation points use needle valves, allowing precise control of flow and pressure in the cavity between the two isolation points, which minimizes leakage and ensures accurate venting. This configuration is particularly suited for instrument and gauge isolation, chemical injection, and sampling applications, where fine control and safety are critical.

The monoflange design integrates the two isolation valves and the bleed into a single compact body. This eliminates the need to bolt together separate valves, reducing the number of joints, potential leak paths, and overall weight, while saving installation space and simplifying maintenance. The valve can accommodate flange sizes from 1/2” to 2” and is rated for Class 150 to Class 2500, making it suitable for a wide range of high-pressure applications.

Manufactured to recognized industry standards including ASME B16.34, API 6D, and ISO 17292, the valve is available in a variety of materials such as SS 316, SS 316L, Duplex, Super Duplex, Hastelloy, Inconel, and Monel. Optional NACE MR-0-175 compliant materials are available for corrosive environments. In-built vent valves and low emission testing ensure the valve meets stringent safety and environmental requirements, providing a reliable solution for critical fluid control applications.

The Tube Fittings Bulkhead Male Connector NPT Thread is a specialized fitting designed to pass tubing securely through panels, enclosures, or bulkheads while maintaining a reliable, leak-tight seal. It is suitable for high-pressure applications up to 6000 PSI and is manufactured according to ASME B16.34, MSS-SP-99, and ASME B31.3 standards, ensuring safety, reliability, and compatibility with industrial systems.

Its bulkhead design allows the tubing to be firmly supported at the barrier, reducing stress on the tubing, preventing vibration-induced leaks, and providing consistent sealing performance under pressure, vacuum, or dynamic conditions.

The NPT male thread enables direct connection to piping, valves, or other threaded components, making installation straightforward and versatile. Precision-machined components ensure that ferrules deform correctly for an optimal seal, while silver-plated threads reduce friction and minimize galling during assembly. Case-hardened ferrules and a robust body material provide durability under repeated assembly or exposure to high vibration, thermal cycling, or corrosive environments.

The design also allows for easy disconnection and retightening without compromising the seal, providing flexibility for maintenance or system changes. Tubing must be properly inserted to the shoulder of the fitting body to ensure maximum sealing efficiency, emphasizing that tubing selection and handling are integral to optimal performance.

Overall, this fitting provides a reliable, high-performance solution for routing tubing through barriers in demanding industrial environments, combining ease of installation, high-pressure capability, and long-term durability with precision engineering suitable for critical oil and gas or process applications.
