Hex Couplings Female NPT are pipe fittings designed to join two male threaded pipes in fluid and gas systems. The female NPT threads provide a tight seal when screwed onto male pipes, ensuring leak-resistant connections. The hexagonal shape allows easy tightening or removal using a wrench, making installation straightforward even in compact spaces.

These fittings are commonly used in oil and gas and process control applications. They are suitable for high-pressure systems, with pressure ratings up to 10000 PSI depending on the material. Hex couplings are available in stainless steel, brass, and carbon steel, offering durability and corrosion resistance in demanding environments.

Sizes available range from 1/8”, 1/4”, 3/8”, 1/2”, 3/4”, to 1”, providing flexibility for different piping setups. Their compact design and reliable performance make them ideal for instrumentation, process piping, and other applications where secure connections are essential.

Square Body Needle Valves Male x Female are engineered for precise flow control and isolation in high-pressure piping systems. The square body design provides a rigid, compact structure that allows for stable mounting, easy wrench access, and alignment during installation. The male and female threaded ends enable secure connections to instrumentation, piping, or process equipment, ensuring leak-tight operation.

These valves are used in oil and gas applications such as connecting impulse lines, controlling flow to pressure transmitters, and isolating instrumentation for maintenance or calibration. The square body allows for easy integration into compact manifolds or tight piping layouts where space and alignment are critical.

Constructed to meet ASME B16.34 and MSS-SP-99 standards, the valves are rated for standard working pressures of 6000 psi, with optional higher-pressure ratings available. They operate effectively over a wide temperature range and are factory-tested for seat and packing leakage, ensuring reliable, consistent performance in demanding field conditions.

The Mini Needle Valve Series – Male x Female is designed for accurate and reliable flow control in small or compact piping systems. Its male-to-female connections allow easy integration into existing instrumentation or process lines. The valve ensures bubble-tight shut-off, preventing leaks in sensitive applications.

The rolled stem threads provide smooth operation, strength, and long service life, while the mirror-finished stem reduces friction, extends packing life, and ensures consistent performance. Packing located below the stem threads prevents lubricant washout, protects against corrosion, and keeps solids from entering the thread area, which could cause damage.

With low operating torque, these valves are easy to operate even in tight spaces. Optional panel-mount versions allow installation in control panels or instrument assemblies, making them ideal for oil and gas, chemical, and other industrial applications where precise flow control is essential.

The HDI 2200 Choke Position Indicator System is a battery-powered, intrinsically safe solid-state electronic gauge designed to monitor choke valve positions in oil and gas operations with high accuracy. It displays choke position in 1% increments from fully closed to fully open (0% to 100%) using a three-digit numeric readout alongside an analog bar graph segmented into 101 divisions for both precise measurement and quick visual trend analysis.

The system interfaces with linear, rotary, or retractable potentiometers housed in stainless steel enclosures. This flexibility allows for straightforward adaptation across many choke configurations without the need for onsite customization. The sealed stainless steel housing and solid-state electronics enable the 2200 to operate reliably in harsh field conditions, including high vibration environments typical in land and offshore drilling.

Its compact display unit measures approximately 8 by 8 by 4 inches and weighs around 5 pounds. The system is powered by an intrinsically safe 3.6V DC battery pack, with a low battery indicator to ensure timely maintenance and uninterrupted operation. Field-repairable components minimize downtime and allow for easy servicing. The system supports dual sensors for integration with human-machine interfaces (HMI) or programmable logic controllers (PLC), enabling remote monitoring and automation. 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.

The Gauge Root Valve Female x Female 1/4” NPT is a small but essential valve used to protect and control pressure instruments, like gauges and transmitters, in fluid or gas systems. Its female x female connection allows it to connect directly to two male-threaded fittings, making installation simple and reducing the risk of leaks.

This valve can handle pressures up to 6000 PSI and operates safely across a wide temperature range. The internal stem is designed with a back seat and the packing is placed below the threads, keeping the threads protected from the process media. A self-centering, non-rotating tip ensures a tight seal every time, preventing leaks.

It also features a removable “T” handle for easy turning with low effort, smooth rolled threads for long-lasting use, and a dust cap to prevent dirt or debris from entering the valve. Each valve is factory tested with nitrogen at 1000 PSI to ensure it seals correctly and operates reliably. This type of valve is ideal for isolating and protecting pressure instruments in chemical, oil and gas, and industrial processes.

The 2 Valve Manifold T Type – Pipe to Flange 1/2” Female NPT is designed to provide a reliable and compact solution for connecting impulse lines to pressure transmitters and gauges. This manifold allows operators to safely isolate instruments from the process for maintenance, calibration, or testing, without the need to shut down the system. The T-type configuration features two valves that control flow to and from the instrument, enabling efficient block, bleed, and vent operations.

The pipe-to-pipe design ensures a direct connection to the piping system, which reduces potential leak points and simplifies installation. It is suitable for high-pressure applications, with a standard working pressure of 6000 PSI and options available for higher pressures. The manifold is built with a metal-to-metal body and bonnet seal for enhanced durability and temperature resistance, with materials that can comply with NACE MR 01 75 standards for corrosion resistance.

Additional features include a removable T-handle for low-torque operation, self-centering non-rotating stems for consistent shutoff, and a dust cap to prevent contamination. Packing is positioned below the stem threads to isolate the threads from the process media, and the stem’s rolled threads provide smooth operation and long life. The manifold is 100% factory tested for leakage and performance, ensuring reliable operation in critical oil and gas applications.

Reducing adapters Female to Male NPT are used to connect pipes or instrumentation lines of different diameters in oil and gas systems. They allow a larger pipe or fitting to join with a smaller one without leaking, ensuring the flow of liquids or gases remains safe and controlled. These fittings are especially useful in situations where space is limited or existing piping needs to be adapted to new equipment.

They are made from high-quality materials such as stainless steel, brass, or carbon steel, which can handle pressures up to 10,000 PSI. The female NPT side threads internally to receive a male pipe, while the male NPT side threads externally to connect to a female fitting. This combination provides a secure, leak-resistant connection that is durable even under high pressure, vibration, or temperature changes.

Reducing adapters are widely used in oil and gas production, processing, and distribution systems.

They are ideal for connecting instrumentation, control systems, chemical injection lines, or any piping where size changes are required. Their compact design and simple installation make them a practical choice for engineers and technicians who need reliable connections in complex piping networks.
