RAY

RAY is a manufacturer of pressure gauge accessories, with a product line centered on snubbers that protect instrumentation from pressure surges and pulsations. The brand's snubbers are used in industrial fluid and gas systems where pressure spikes can degrade gauge accuracy or cause mechanical failure. 3G Electric supplies RAY snubbers globally, with current stock including filter-type models in 303 stainless steel and brass, all with NPT connections. These snubbers are specified for oil, water, air, and compatible gases, and are available in configurations with zero pistons, indicating a filter-based damping mechanism rather than a piston-based one. The product range includes models such as the 747SE, 747SD, 723SE, 747SG, 747BG, 722SG, 747BD, and 723SD, each differentiated by material, connection type, and intended media. Stainless steel models are constructed from 303 stainless steel, which provides corrosion resistance for use with water, oil, and various gases. Brass models, such as the 747BG and 747BD, are rated for a maximum pressure of 3,000 psi and are intended for gas and oil applications, respectively. All listed models use NPT connections, a standard thread form for industrial piping in many regions. The filter-type design allows the snubber to dampen pressure fluctuations by restricting flow through a porous element, which smooths erratic pressure readings and reduces wear on gauge internals. This is particularly relevant in hydraulic and lubrication systems, pneumatic lines, air compressors, and gas distribution networks where pressure transients are common. RAY snubbers are typically installed directly upstream of pressure gauges, and their compact form factor allows for inline mounting without significant space requirements. The use of 303 stainless steel offers good machinability and moderate corrosion resistance, suitable for many industrial environments, while brass provides an alternative for applications where stainless steel is not required. 3G Electric supports the RAY line by maintaining inventory of these snubbers and providing global shipping. Technical buyers can reference the MPN and specifications to select the appropriate model based on media, material, and pressure rating. The product data includes details such as snubber type, material, connection type, and maximum pressure, enabling informed procurement decisions. For applications requiring protection of pressure gauges from surges and pulsations in oil, water, air, or gas, RAY filter-type snubbers offer a straightforward solution. 3G Electric's catalog includes these items with clear specifications, and the company serves plant engineers, maintenance managers, and procurement specialists worldwide. The RAY brand is known for these pressure gauge accessories, and 3G Electric's role is to make them accessible with accurate product information and efficient order fulfillment.

Common Applications

  • Hydraulic systems — RAY 747SD or 723SD filter-type snubbers protect pressure gauges from surges in oil lines.
  • Pneumatic systems — RAY 747SG or 747BG snubbers dampen pulsations in air and gas lines to stabilize gauge readings.
  • Lubrication systems — RAY 723SE stainless steel snubbers shield gauges from pressure spikes in oil circulation circuits.
  • Water treatment — RAY 747SE filter-type snubbers reduce pressure fluctuations in water lines to extend gauge life.
  • Air compressors — RAY 722SG snubbers smooth erratic pressure output before the gauge to prevent needle flutter.
  • Gas distribution — RAY 747BG brass snubbers rated to 3,000 psi protect gauges in gas service where brass is acceptable.

Frequently asked questions

Common questions about RAY from 3G Electric.

What is the difference between RAY filter-type snubbers and piston-type snubbers?

RAY filter-type snubbers, such as the 747SE and 723SE, use a porous filter element to dampen pressure surges and pulsations. They contain zero pistons, as indicated in the specifications. Piston-type snubbers, by contrast, use a moving piston to restrict flow. Filter-type models are often chosen for applications where the media is relatively clean and a compact, maintenance-free design is preferred. The filter-type construction is suitable for oil, water, air, and compatible gases, and provides a simple inline solution for protecting pressure gauges.

What materials are used in RAY snubbers and what are their pressure ratings?

RAY snubbers are available in 303 stainless steel and brass. Stainless steel models, such as the 747SE, 747SD, 723SE, 747SG, 722SG, and 723SD, offer corrosion resistance for use with water, oil, and gases. Brass models, including the 747BG and 747BD, are rated for a maximum pressure of 3,000 psi. All models use NPT connections. The material choice depends on the media and environmental conditions; stainless steel is typically selected for more corrosive or demanding applications, while brass is used where the media is compatible and a lower-cost material is acceptable.

Which RAY snubber models are suitable for oil applications?

Several RAY filter-type snubbers are designed for oil service. These include the 747SD, 723SE, 723SD, and 747BD. The 747SD, 723SE, and 723SD are constructed from 303 stainless steel, while the 747BD is made of brass and rated to 3,000 psi. These models protect pressure gauges from surges and pulsations in hydraulic and lubrication systems. When selecting a snubber for oil, consider the system pressure, temperature, and compatibility of the construction material with the specific oil used.

Can RAY snubbers be used with gases such as air or compressed gases?

Yes, RAY offers filter-type snubbers specifically for gas applications. The 747SG is a 303 stainless steel model designed for gases, and the 747BG is a brass model rated to 3,000 psi for gas service. The 722SG is another stainless steel option suitable for air. These snubbers dampen pressure surges and pulsations in pneumatic lines, air compressors, and gas distribution systems. They help maintain stable pressure readings and protect gauge mechanisms from erratic pressure fluctuations.

What connection type do RAY snubbers use?

All RAY snubbers listed in 3G Electric's catalog use NPT (National Pipe Thread) connections. NPT is a widely used standard for industrial piping in many regions. The specific NPT size may vary by model; refer to the individual product specifications for the exact thread size. NPT connections provide a reliable, leak-resistant seal when properly installed with appropriate sealant or tape. This connection type allows for direct installation into gauge ports or adapters.

How do I select the correct RAY snubber for my pressure gauge application?

Selection depends on the media (oil, water, air, or gas), the system pressure, and the environment. For oil and water, stainless steel models like the 747SE or 723SE are common. For gases, consider the 747SG or 747BG. If the maximum pressure is up to 3,000 psi and brass is compatible, the 747BG or 747BD may be suitable. All models have zero pistons and use NPT connections. Verify the pressure rating and material compatibility with your system. 3G Electric provides detailed specifications for each RAY snubber to assist in selection.
