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 HDI 1000P Pressure Gauge System is a battery-powered, intrinsically safe electronic gauge used to monitor high-pressure systems in oil and gas operations. It measures pressure using a strain gauge sensor and provides real-time readings on a digital display with both numeric and bar graph formats. Common applications include choke manifolds, cementing units, coiled tubing, and high-pressure pumping systems.

With pressure ranges available from 5,000 psi up to 30,000 psi, the 1000P is suitable for demanding environments. It offers ±0.5% full-scale accuracy, and optional 4-20mA or 0–1 VDC outputs for integration with PLCs or remote monitoring systems. The unit is housed in a sealed stainless steel enclosure and built to perform reliably in harsh, high-vibration field conditions.

Designed for ease of use, the 1000P includes a field-replaceable battery pack and supports a range of connection types such as 2" 1502, 2002, 2202, or flanged. Its solid-state platform minimizes maintenance and ensures consistent performance over time, making it a dependable tool for critical pressure monitoring tasks.

The Monoflange DBB Double Block & Bleed Valve Flange x Thread with OS&Y and Needle Isolation is designed to provide reliable dual isolation with a controlled bleed in a single assembly. This configuration replaces the need for multiple individual valves, reducing the number of potential leak points and simplifying installation in oil and gas applications. The first isolation is achieved using an OS&Y valve, while the second isolation and the drain function use a needle valve, providing precise control over fluid venting and depressurization.

This valve is suitable for instrument and gauge isolation, chemical injection points, sampling connections, and direct or remote mounting of instruments. It supports high-pressure systems with a range from Class 150 to Class 2500, and accommodates both reduced and full bore options. Constructed from durable materials including SS 316, SS 316L, Duplex, Super Duplex, Hastelloy, Inconel, and Monel, the valve can also be supplied with NACE-compliant materials on request.

Manufactured in accordance with recognized standards such as ASME B16.34, API 6D, and ISO 17292, the Monoflange DBB provides a compact, robust solution for dual isolation with reliable venting. Its integrated design reduces stress on piping systems, minimizes maintenance needs, and ensures consistent performance in critical oil and gas applications.

The HDI 1522 Choke Position Indicator System is an electronic instrument designed to accurately measure and display the position of choke valves used in oil and gas production. Choke valves regulate the flow of oil, gas, or water from wells by adjusting the degree of restriction in the pipeline, which directly affects pressure control and production rates. The 1522 system provides highly precise position readings in one percent increments, ranging from fully closed (0%) to fully open (100%), enabling better management of well performance and enhanced safety.

This system uses solid-state electronics to convert mechanical valve movement into electronic signals via various potentiometer types—including linear, rotary, and retractable options—making it adaptable to a wide variety of choke valve designs and configurations. The position data is presented on a four-inch liquid crystal display that combines a numeric readout with a linear bar graph, allowing clear and immediate visualization of the choke’s exact position. The display is engineered for visibility from distances up to fifteen feet, suitable for typical field environments.

Powered by an internal, field-replaceable battery with approximately one year of continuous operation, the 1522 system minimizes maintenance requirements and eliminates the need for complex wiring. It also offers optional analog output signals, such as 4-20 mA or 0-1 V, enabling seamless integration with plant control systems, programmable logic controllers, data acquisition systems, or remote display units for centralized monitoring and automation.

The enclosure is constructed from UV-stabilized, impact-resistant polycarbonate and PBT alloy materials to ensure durability in harsh outdoor conditions. It is rated to operate reliably within a wide temperature range from -40°F to 176°F (-40°C to 80°C). The internal electronics are protected by a gasket seal to prevent dust and moisture ingress, maintaining performance and longevity.

Installation flexibility is enhanced through support for cable lengths up to 1,500 feet, allowing the gauge to be mounted in the most accessible or secure locations. Multiple sensor housing options and connector orientations simplify field installation and reduce the need for onsite customization, helping to minimize downtime and installation costs.

The 1522 Choke Position Indicator System delivers accurate, real-time choke valve position information in a robust, easy-to-install package. Its reliable performance, flexible integration capabilities, and low maintenance design support improved flow control, safer operations, and optimized production.

The Gauge Root Valve Male x Female with Lagging Extension in 1/4” NPT is a small but robust valve used to safely isolate pressure gauges in pressurized systems. It is designed to handle pressures up to 6000 PSI and temperatures from -50°C to 230°C, providing a reliable seal and leak-free operation. The lagging extension lets the valve be operated without removing insulation, protecting both the system and the operator.

The valve includes features to make it safe and easy to use: a back seat on the stem for extra security, a self-centering non-rotating tip for consistent shutoff, and an adjustable gland retainer to keep the packing tight. The removable T-handle allows smooth operation with minimal effort, while the dust cap prevents dirt or debris from entering the valve. All valves are factory tested for performance, include heat code traceability, and can be made from materials compliant with NACE MR 01-75 for corrosion resistance.

This valve is ideal for oil and gas systems where isolating gauges safely, maintaining insulation, and ensuring reliable operation are essential.

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.
