Midland Industries 34051 Pol X 5/8 Flared Brass Adapter

Product Description

The MIDLAND INDUSTRIES 34051 is a brass POL-to-flare adapter designed to connect LP gas regulators and cylinders to downstream tubing or appliance connections. The first end is a 0.88-14 LH (left-hand) POL male fitting, which is the standard connection for propane cylinder valves. The second end is a 5/8 inch flare fitting. Machined from brass, this adapter provides a durable, corrosion-resistant connection point in low-pressure LP gas distribution systems. It is compact at approximately 2.15 inches in length and weighs under 0.25 pounds, making it easy to handle during installation in tight spaces.

This adapter is used in residential and light commercial LP gas systems where a regulator outlet or cylinder valve must transition to a flared tubing connection. Typical applications include connecting a POL-style propane cylinder valve to flared copper or brass tubing feeding a gas appliance, outdoor grill manifold, or portable LP equipment. Plumbers and gas fitters working on propane distribution systems reach for this fitting when transitioning between the POL interface and standard flare tubing runs.

Key Features

• 0.88-14 LH POL male connection matches standard propane cylinder valve threads
• 5/8 inch flare female end accepts standard flared tubing connections
• Left-hand thread on POL end prevents accidental cross-threading with right-hand fittings
• Brass construction resists corrosion in LP gas service
• Compact profile at 2.15 inches length for use in confined installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for LP gas systems using 0.88-14 LH POL cylinder or regulator connections transitioning to 5/8 inch flared tubing.

Installation Notes

Installation should be performed by a licensed plumber or qualified gas fitter in accordance with NFPA 54, NFPA 58, and applicable local codes. Always close the propane cylinder valve and verify zero pressure in the line before making or breaking any connections. Inspect flare seats for damage before assembly and do not use thread sealant on flare connections. Tighten to a snug fit and leak-test all joints with an approved leak-detection solution before returning the system to service.
