4403240 - Harris Pipeliner Classic AF Deluxe Propane Cutting Outfit

Technical Overview

The Harris Pipeliner Classic AF (Alternate Fuel) Cutting Outfit, SKU 4403240, is a comprehensive industrial solution designed specifically for operation with oxygen and propane or natural gas. This kit is built around the Model 43-2 heavy-duty torch handle and the Model 49-3F cutting attachment. The 'F' designation indicates a low-pressure injector mixing system, which is critical for alternate fuels; it creates a venturi effect to pull the fuel gas into the mixing chamber, ensuring a stable flame and maximum thermal efficiency that standard equal-pressure mixers cannot achieve with low-pressure fuels.

Pressure regulation is managed by the Harris Model 425 series regulators. These single-stage, heavy-duty regulators are engineered with a one-piece encapsulated seat design featuring an internal filter and a PTFE Teflon seat. This construction minimizes failure points and protects the high-pressure seat from particulate contamination, a common cause of regulator creep. The regulators are equipped with large 2.5-inch dual-scale brass gauges and a brass 'T' screw adjusting handle for precise flow control. The fuel gas regulator is specifically calibrated for LP gas pressures.

The Model 49-3F cutting attachment utilizes brazed triangular stainless steel tubes, providing a superior strength-to-weight ratio compared to standard round tubes. The solid forged brass head resists distortion from heat and abuse. Safety is enhanced by the inclusion of FlashGuard check valves on the torch handle, preventing reverse flow conditions. The kit comes complete with a 20-foot Grade T twin hose, which is chemically compatible with all fuel gases, ensuring the lining does not degrade when used with propane.
