This valve is ideal for isolating and protecting pressure measurement instruments.

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 Bore Through Male Connector NPT fittings are engineered to create robust, leak-free connections in high-pressure systems. These fittings feature a bore-through design, allowing fluid or gas to flow freely without obstruction, which minimizes pressure drop and ensures consistent system performance. Made from high-quality materials, they are suitable for pressures up to 6000 PSI and are manufactured to meet ASME B16.34, MSS-SP-99, and ASME B31.3 standards.

The NPT (National Pipe Thread) male connection ensures a tight seal when connected to compatible threaded components, providing reliable performance in oil and gas, chemical, and process industries. The fittings are precision-machined for proper ferrule deformation, which ensures leak-free connections under vibration, impulse, or vacuum conditions. Silver-plated threads reduce friction and prevent galling, while the bore-through design supports high flow rates without obstruction.

Bore Through Male Connector NPT fittings are easy to install and maintain. They are finger-tight for initial assembly and then wrench-tightened to achieve a secure seal, reducing installation errors and downtime. Their design allows disconnection and reconnection without compromising sealing integrity, making them suitable for applications requiring frequent maintenance or system modifications.

These fittings are unique in combining full-flow capability, high-pressure performance, and reliable sealing in a compact, easy-to-install form, making them ideal for demanding oil and gas systems, process lines, and high-pressure instrumentation setups.

The Double Block & Bleed Valve – Flange x Flange – Ball x Ball with Needle Drain is a high-performance isolation and venting solution designed specifically for oil and gas applications.

Its compact, space-saving design reduces potential leak paths compared to conventional multi-valve assemblies, lowering installation costs and improving reliability.

HDI Gauge systems used in oil and gas operations are often exposed to harsh environments and continuous use. To maintain accuracy, reduce downtime, and extend the service life of these systems, it is critical to have access to replacement components that are both durable and compatible. A full range of spare parts is available to support maintenance needs, including displays, sensors, cables, processor boards, connectors, and housing elements.

These parts are designed to be interchangeable across compatible models, allowing operators to replace worn or damaged components without requiring full system replacement. This modularity improves cost efficiency and simplifies logistics, especially in remote field locations. Most components are field-replaceable, reducing the need for specialized service technicians and enabling faster return to operation.

Processor boards and display units typically share a common design across multiple gauge models, streamlining inventory requirements and providing flexibility during urgent repairs. Sensors are matched with gauge heads for calibration accuracy but can be easily re-paired and recalibrated in the field or through service support if needed.

Using certified or manufacturer-specified replacement components ensures continued compliance with safety standards, maintains the expected measurement accuracy, and supports the longevity of the equipment. These parts are often backed by service documentation or part tracking for maintenance records and equipment history management.

In short, a well-organized supply of compatible, high-quality parts is essential for effective pressure and temperature gauge system upkeep in demanding industrial settings.
