omponent Name

Pressure Snubber – Stainless Steel 304

(Also called: Gauge Snubber / Pulsation Dampener)

🧱 Material Specifications

• Body Material: Stainless Steel 304

• Internal Element:

  • Porous sintered SS

  • Or piston / disc type (manufacturer dependent)

• Standard Material Specs:

  • ASTM A276 / A479

• Finish: Natural / Passivated

🔩 End Connections

• Process Connection:

  • 1/4" or 1/2" NPT (Male or Female)

• Instrument Connection:

  • 1/4" or 1/2" NPT (Male or Female)

• Thread Standard:

  • ASME / ANSI B1.20.1

⚙️ Operating Principle

• Restricts sudden pressure surges using:

  • Porous element (most common)

  • Piston type (for severe pulsation)

• Smooths pressure fluctuations before they reach the gauge or transmitter

💪 Pressure Rating (Typical)

• Up to 6000 psi (≈ 413 bar)
  (Depends on design and connection size)

🌡️ Temperature Range

• SS 304:

  • –20 °C to +200 °C (standard)

  • Higher temperatures possible with special internals

🧪 Media Compatibility

Suitable for:

• Air & gas

• Water & steam

• Hydraulic oil

• Fuel

• Mild chemicals (non-chloride rich)

For corrosive media, SS316 is generally preferred.

📐 Types Available

• Fixed snubber (non-adjustable)

• Adjustable snubber (needle-controlled)

• Piston type (heavy pulsation service)

🛠️ Installation Notes

• Install between process line and pressure gauge/transmitter

• Orientation:

  • Any position (unless specified)

• Use PTFE tape or thread sealant

• Do not over-tighten

• Clean periodically if clogging occurs

🏭 Typical Applications

• Pressure gauges

• Pressure transmitters

• Reciprocating pumps

• Compressors

• Hydraulic systems

• Instrument impulse lines
