Dixon Valve Coupling CAB200 Suction Coupling Npsm

Product Description

The DIXON VALVE COUPLING CAB200 is an aluminum suction coupling designed for use in fluid transfer systems requiring a secure, leak-resistant connection. This complete coupling features a short shank profile and NPSM (National Pipe Straight Mechanical) threading, which allows for easy hand-tight assembly without the need for tapered pipe sealing. The lightweight aluminum construction keeps overall weight low at 0.1 pounds, making it practical for repeated installation and removal in service environments. Plumbers, irrigation technicians, and industrial service professionals install this fitting in suction-side piping runs where a straight-thread mechanical seal is preferred over tapered NPT connections.

The CAB200 is suited for suction-line applications in water transfer, pump intake plumbing, and similar fluid-handling systems. The short shank style makes it appropriate for installations with limited clearance or where compact coupling geometry is required. Its aluminum body resists corrosion in many common fluid environments, making it a reliable choice for both field service and fixed installations in light industrial and commercial settings.

Key Features

• NPSM straight mechanical thread for hand-tight, no-taper sealing
• Short shank design suits tight-clearance installations
• Aluminum construction provides corrosion resistance and low weight
• Complete coupling configuration — ready to install as received
• Lightweight at 0.1 pounds for easy handling in the field

Compatibility

Designed as an OEM-style replacement or service fitting for suction-side piping systems using NPSM straight mechanical threaded connections in pump and fluid transfer applications.

Installation Notes

Installation is typically performed by licensed plumbers or fluid systems technicians. Shut off and depressurize the system completely before removing or installing any coupling. NPSM threads are straight and rely on a mechanical seal rather than thread interference, so ensure mating threads and sealing surfaces are clean and undamaged before assembly. Follow applicable IPC and local plumbing code requirements for fluid transfer fittings.
