Conbraco 27-402-01 Steam Gauge Siphon 1/4" 90 Degree Angle Brass

The Conbraco 27-402-01 is a 1/4" steam gauge siphon featuring a 90-degree angle loop design in brass construction. This pigtail siphon is an essential protective device installed between steam lines and pressure gauges to prevent damage from high-temperature steam and pressure surges.

How It Works:

The distinctive looped "pigtail" design creates a natural trap where condensate accumulates, forming a liquid barrier that protects sensitive pressure gauge components. When steam enters the siphon, it cools and condenses within the loop, ensuring only cooler liquid reaches the gauge rather than direct high-temperature steam contact. Before installation, the siphon should be filled with water to create an immediate protective barrier.

Key Features:

• 1/4" NPT brass construction for durability and corrosion resistance
• 90-degree angle loop configuration for vertical piping applications
• Protects pressure gauges from steam temperatures that can exceed gauge operating limits
• Reduces damage from rapid pressure surges and pulsations
• Brass finish suitable for industrial steam applications
• Compatible with standard pressure gauges rated up to 200-250°F

Applications:

Ideal for steam boiler systems, industrial steam lines, power generation facilities, refineries, and any application where pressure measurement is required in steam service. The 90-degree design is specifically intended for vertical piping configurations where the gauge will be mounted at a right angle to the steam line.

This Conbraco/Apollo Valves siphon is manufactured to industry standards and provides reliable protection for your pressure instrumentation, extending gauge life and ensuring accurate pressure readings in demanding steam applications.
