Gauge adapters with a female ISO parallel thread to male NPT are small but essential components used to connect measurement instruments, such as pressure gauges or transmitters, to piping systems in industrial and oil and gas applications.

The female ISO thread screws directly onto the instrument, while the male NPT thread connects securely to the pipe or tube, creating a tight and leak-resistant connection.

These adapters are made from high-quality materials such as stainless steel or brass, which makes them durable and resistant to corrosion, even in harsh environments. They are designed to handle high pressures, up to 10,000 PSI, ensuring that instruments provide accurate readings without risk of failure.

They follow international thread standards including ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228, which guarantees compatibility with other equipment and ensures reliable performance in critical systems. This makes them a practical and dependable choice for monitoring and controlling fluids.

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.

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 5 Valve Manifold R Type – Pipe to Pipe is designed for high-pressure oil and gas applications where differential pressure transmitters or gauges need to be connected, calibrated, and maintained safely. This manifold provides two block valves, two equalizer valves, and one bleed valve in a single assembly, allowing operators to isolate the transmitter, equalize pressure between impulse lines, and safely vent pressure when required.

The R Type configuration is particularly suitable when multiple valve functions are needed in a compact layout. By combining all five valves in one manifold, it reduces the number of separate components, minimizes potential leak points, and saves installation space compared to using individual valves.

This manifold is ideal for environments where reliability and safety are critical, offering 6000 PSI standard working pressure, metal-to-metal sealing for high-pressure and temperature performance, and compatibility with NACE MR 01 75 materials. Its design ensures smooth operation, low torque handling, and long-term durability, making it the preferred choice for complex measurement and control systems in oil and gas operations.

The Tube Fittings Male Elbow NPT is a mechanical fitting that provides a 90° connection between tubing and components with National Pipe Taper (NPT) threads. It is designed for use in high-pressure systems with operating pressures up to 6000 PSI.

The elbow configuration allows tubing runs to change direction while maintaining a sealed joint. Threads are tapered in accordance with NPT standards to create a pressure-tight seal when properly installed.

These fittings are produced in a range of sizes from 1/4” to 1” and are manufactured in line with ASME B16.34, MSS-SP-99, and ASME B31.3 requirements. Typical applications include oil, gas, and industrial process systems where tubing must be connected to threaded equipment or piping at an angle.

The Monoflange SBB Double Block and Bleed Valve with Flange x Thread connections features an OS&Y isolation valve and a needle drain, providing dual isolation in a single compact assembly. It is designed for oil and gas applications where safe venting of trapped pressure between isolation points is required, such as instrument or gauge isolation, chemical injection, and sampling lines.

The valve’s monoflange design integrates both isolation and venting functions in one unit, reducing the number of joints and potential leak paths while saving space and simplifying installation. The OS&Y isolation valve offers clear visual indication of open or closed status, allowing operators to quickly verify valve position. The needle drain provides controlled venting of pressure trapped between the isolation points, ensuring safe operation during maintenance or sampling procedures.

The valve is suitable for flange sizes from 1/2” to 2” and pressure classes from 150 to 2500, with options for reduced or full bore depending on process requirements. It is available in a variety of materials including stainless steel 316, 316L, duplex, super duplex, Hastelloy, Inconel, and Monel, and can be manufactured to meet NACE MR-0175 standards. The design complies with recognized standards such as ASME B16.34, API 6D, and ISO 17292, and is tested to low emission requirements.

This configuration is ideal for oil and gas operations requiring reliable dual isolation, precise venting, and compact installation in critical piping systems.

Close Nipples Male NPT are precision pipe fittings designed to connect two female NPT threaded pipes in oil and gas and process systems. Their short, compact design allows installation in tight spaces while providing a reliable and leak-tight connection.
