Norgren 17-816-998 Drip Leg Drain - Automatic Drain, G1/2
Part Number: 17-816-998
Quick Summary
Norgren drip leg drain is an automatic condensate drain designed for compressed air systems. It automatically expels liquids from the piping network, helping keep lines dry and prevent moisture-related issues in downstream equipment. In line with common industry practice, this unit is built with a zinc body and zinc bowl, nitrile rubber elastomer seals, and a robust G1/2 port that supports up to 16 bar inlet pressure. Ideal for installation at low points and at the far end of long piping runs, it reduces condensate carryover and maintenance needs while boosting system reliability and uptime. Designed for compatibility with standard pneumatic components, it delivers reliable, maintenance-free condensate removal and supports efficient plant operations and reduced total cost of ownership.

FAQs
The 17-816-998 uses a common G1/2 port, aligning with standard compressed air fittings and Norgren-mate components. It installs at low points or remote ends of lines and integrates into typical pneumatic layouts without special adapters. Ensure the connection hardware matches the port threading and that line pressure stays within the 16 bar maximum to maintain reliable drainage.
This drain is rated for up to 16 bar of inlet pressure and operates from -20 °C to 80 °C (-4 °F to 176 °F). These limits support most industrial environments, including plants with fluctuating temperatures and variable pressure regimes, while maintaining automatic condensate expulsion and system protection.
The unit features zinc body and zinc bowl with nitrile elastomer seals, suitable for general industrial use. For harsh or food-grade environments, verify local requirements and consider surface treatments or alternative materials. If specific certifications are required, consult the supplier for CE labeling, IP ratings, or SIL compatibility as applicable to your installation.
The drain is designed for maintenance-free operation under normal conditions, relying on float-activated, automatic operation. Regular inspections during routine maintenance cycles should verify seal integrity and absence of blockages. If condensate handling is impaired, inspect for corrosion, gasket wear, or debris that could affect float movement and replace parts as needed.
By eliminating manual condensate draining, the 17-816-998 reduces downtime, protects downstream equipment from water damage, and decreases maintenance labor costs. Over time, this translates to higher system reliability, prolonged component life, and lower total cost of ownership in compressed air networks, particularly in facilities with frequent condensate generation.
