Neuco 12a09 Vent Limiter 1/8 Inch Npt Natural Gas Lp

Product Description

The NEUCO 12a09 is a green 1/8 inch NPT vent limiter designed for use on 2 psi gas regulator applications. This fitting controls vent port flow on compatible gas pressure regulators, protecting the regulator vent from backpressure conditions while allowing safe venting of the regulator body. It is certified for use with natural gas at up to 5 psi and with LP gas at up to 2 psi. Licensed gas technicians and HVAC service professionals install this component during regulator service or new regulator installations on residential and light commercial gas supply systems.

The 12a09 vent limiter is intended for use with 2 psi gas distribution and appliance regulator systems. It is specified for use with the 325-3 and 323-3L regulator models. Typical applications include residential and light commercial gas piping systems where low-pressure regulation is required at the appliance or service entry point. The green color coding aids field identification of the correct vent limiter for the applicable pressure range.

Key Features

• 1/8 inch NPT thread connection for direct installation on regulator vent port
• Certified for natural gas service up to 5 psi

• Green color coding identifies 2 psi pressure range application
• Compatible with 325-3 and 323-3L regulator models

Compatibility

Designed for use with the 325-3 and 323-3L gas pressure regulators. Suitable for 2 psi natural gas and LP gas regulator vent port applications.

Installation Notes

Installation must be performed by a licensed gas technician or qualified HVAC professional in accordance with local codes and IFGC requirements. Shut off the gas supply and verify zero pressure at the regulator before removing or installing any vent fitting. Thread the vent limiter into the regulator vent port by hand first to avoid cross-threading, then tighten with an appropriate wrench. Verify there are no gas leaks at the connection after restoring supply pressure.
