QC Hydraulics’ Tube Stub Hose Fittings for PTFE hoses are hydraulic fittings designed to connect PTFE (Teflon) hoses to tubing via a stub end, typically paired with twin-ferrule compression tube fittings for a secure, leak-proof joint. Often made of stainless steel, they attach to the hose through crimping or clamping, eliminating threads. These fittings are ideal for high-pressure, corrosion-resistant applications like hydraulics or chemical transfer with PTFE hoses, providing a robust, streamlined connection.
