Dixon Valve Coupling 3512 Barbed Hose Fitting

Product Description

The DIXON VALVE COUPLING 3512 is a barbed hose fitting designed to create secure, leak-resistant connections between hose sections or between a hose and a fluid-carrying system component. Barbed fittings rely on interference fit between the barb geometry and the inner diameter of the hose, holding the assembly under pressure without additional fasteners. This fitting weighs 1 pound and is suited for fluid transfer applications across plumbing, HVAC condensate lines, irrigation, and general industrial service. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this type of fitting.

Barbed hose fittings in this class are used wherever a flexible hose must be joined to a port, manifold, or mating hose segment. Typical install scenarios include condensate drain assemblies, low-pressure water lines, pneumatic tubing runs, and chemical transfer setups in light commercial or residential environments. The fitting accommodates flexible hose materials including PVC, rubber, and polyethylene, depending on hose inside diameter compatibility.

Key Features

• Barbed retention geometry creates a secure grip on flexible hose without additional clamps in low-pressure service
• Compact, single-piece construction with no moving parts
• Weighs 1 pound, suited for portable or fixed-line installations
• UNSPSC classified under fluid handling fittings (40141734)

Compatibility

Designed as an OEM-style replacement or new-installation barbed hose fitting for use in residential and light commercial fluid transfer systems where flexible hose termination or inline joining is required.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians. Shut off fluid supply and relieve system pressure before fitting removal or installation. Push hose firmly over all barbs and secure with an appropriate hose clamp when system pressure or vibration demands a retained connection. Verify hose inside diameter matches the fitting barb size before assembly to ensure a pressure-rated seal.
