The 1/4" poppet type check valve with male × female NPT connections is designed to allow fluid flow in one direction while preventing backflow in oil and gas systems. Its poppet design provides fast response and reliable sealing under pressure, ensuring protection of pipelines, pumps, and other critical equipment from damage caused by reverse flow or pressure fluctuations.

The 1/4" size is ideal for small diameter lines, instrumentation, sampling, or control applications where space is limited and precise flow control is required. Male × female connections allow secure inline installation and integration into existing piping without the need for additional fittings, reducing potential leak points and simplifying system layout.

Factory tested for cracking and reseal performance, the valve has a standard working pressure of 6000 psi, with optional ratings up to 10000 PSI. It offers selectable cracking pressures from 1/3 to 25 psi, making it adaptable to various flow requirements. The valve is available in corrosion resistant materials such as SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, suitable for demanding oil and gas environments. Heat code traceability ensures quality and material verification, and additional testing options including vibration, temperature, and helium testing are available for critical applications.

Tube Fittings Male Connector NPT are used to connect tubing directly to threaded pipe systems, ensuring a secure and leak-tight joint in fluid and gas applications. The male NPT threads allow compatibility with standard pipe threads.

These fittings are unique due to their twin ferrule design, which provides a strong mechanical grip on the tubing while creating a reliable seal without requiring welding or additional sealants. The precision-machined ferrules deform evenly to prevent leaks, even under vibration, impulse, or high-pressure conditions.

Straight fittings are manufactured from bar stock, and shaped fittings are made from forgings, offering high structural strength. The case-hardened back ferrules and silver-plated female threads reduce wear and prevent galling, while the radius junction in elbows maintains smooth flow.

Installation is simplified: the tubing is inserted fully to the shoulder of the fitting, and the nut is tightened to specific torque, producing a secure connection. Male Connector NPT fittings are ready for immediate use and can be disassembled and retightened if needed.

Their combination of threaded pipe compatibility, twin ferrule sealing, and ease of installation makes them reliable and widely used in demanding industrial applications.

The HDI 2000B Pressure Gauge System is a panel-mounted electronic device designed to measure and display high-pressure levels accurately in industrial and oilfield settings. It monitors pressures up to 20,000 psi with an accuracy of plus or minus 0.50 percent of full scale, making it suitable for critical applications where precise pressure monitoring is essential for safety and operational control.

The system consists of two main components: a digital gauge display and a remote pressure sensor connected by an interconnect cable. This design allows the sensor to be installed directly at the pressure source, such as a wellhead, pump, or manifold, while the display is mounted in a more accessible location for easy reading and monitoring.

The gauge features a six-inch liquid crystal display that combines a five-digit numeric readout with an analog bar graph composed of 101 segments. This clear and detailed display makes it easy to quickly understand both the exact pressure value and its trend, even in low-light or harsh environments. The display can be read from up to 35 feet away.

Power is supplied by a replaceable 3.6-volt battery designed to last between 12 and 18 months under continuous operation. Calibration and configuration data are stored in memory that does not require power, ensuring settings remain intact even when the battery is replaced or the system is powered off.

The pressure sensor employs strain gauge technology and is compatible with a wide range of connection types including standard pipe threads and flanges. This allows the system to be used across various equipment and pressure ranges, while simplifying maintenance by enabling cross-compatibility of sensors.

Optional analog outputs provide 4–20 mA or 0–1 volt signals to connect the gauge to control systems, data loggers, or remote displays. This supports centralized monitoring and integration with automated process control.

In oil and gas operations, the 2000B system is commonly used to monitor pressure at wellheads to ensure safe extraction pressures, on pumps to maintain correct fluid flow and prevent overpressure damage, and on manifolds to track pressure differentials between flow lines. Accurate, real-time pressure data from this system helps operators detect anomalies early, avoid equipment failure, and optimize production rates while maintaining safe operating conditions. Its robust design and modular installation make it well-suited for harsh field environments where reliability and ease of maintenance are critical.

The HDI 3300 Temperature Gauge System is an intrinsically safe, battery-powered electronic temperature measurement device commonly used in oil and gas operations requiring precise temperature monitoring. Typical applications include high-pressure nitrogen pumping, geothermal and mud-based drilling, well control manifolds, flare stacks, and bulk liquid storage.

The system consists of a digital gauge display, sensor assembly, and interconnecting cable. The sensor, usually a Resistance Temperature Detector (RTD), is housed in a durable stainless steel case with various mounting options like 2-inch Male NPT, hammer unions, or flanges, allowing flexible installation near the temperature source.

The display features an LCD with numeric and analog bar graph outputs, providing temperature readings with 0.1-degree resolution and ±0.5% full-scale accuracy over a range of -50 to 150°C (-50 to 300°F). Users can switch between Celsius and Fahrenheit. It includes 4-20mA and 0-1 VDC output options for integration with remote monitoring, data logging, or control systems, and supports external power inputs.

Designed for ease of maintenance, the system is field-repairable with a replaceable battery pack. The sensor and display are factory-matched and calibrated, requiring recalibration if components are replaced. The gauge fits standard 6-inch panel cutouts and supports multiple mounting patterns. Cable lengths are customizable up to 200 feet or more.

The system operates reliably in temperatures from -40°C to +70°C and is certified for hazardous environments, with a rugged stainless steel sensor housing to withstand harsh field conditions.

The 3300 is well-suited for environments requiring precise, continuous temperature monitoring, including high-pressure drilling, well control, and fluid storage applications. Its intrinsically safe design provides dependable operation in hazardous locations without compromising safety. The solid-state electronics and durable construction reduce maintenance and downtime, while versatile mounting options allow placement close to the measurement point for accurate readings. Featuring clear numeric and bar graph displays along with remote output capabilities, the system supports timely decision-making and integrates easily with larger monitoring setups, enhancing process control and operational safety in demanding conditions.

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.
