B Type 3" Aluminum Camlock - Female Coupler x Male NPT

The B Type 3" Aluminum Camlock is a heavy-duty cam and groove coupler with a 3" female camlock (cam & groove) on one side and a 3" male NPT thread on the other. It provides a fast, leak-resistant way to connect lay flat discharge hose or suction hose to pumps, valves, tripods, and manifolds in agricultural and industrial water systems.

Use this fitting anywhere you want a quick-connect / quick-disconnect connection that can be opened without tools – perfect for trash pumps, transfer pumps, portable irrigation setups, and water-moving jobs where hoses are connected and disconnected often.

Key Features

• Standard Type B camlock – 3" female cam & groove coupler x 3" male NPT.
• Lightweight aluminum body – durable and corrosion-resistant for water and most agricultural and industrial applications.
• Quick, tool-free connection – close the two cam arms to lock the fitting; lift to release.
• Compatible with 3" male camlock adapters on lay flat hose, suction hose, and pipe ends.
• Reusable & field-serviceable – replaceable gasket and cam arms (when parts are available).

How This Fitting Connects

On the camlock side (hose / adapter side):

• Insert the 3" male camlock adapter (on your lay flat hose, suction hose, or pipe) fully into the female camlock coupler.
• Close both cam arms at the same time until they are fully locked down.
• The gasket inside the coupler compresses around the adapter for a tight, leak-resistant seal.

On the threaded side (pump / pipe side):

• Thread the 3" male NPT end into any 3" female NPT port on pumps, valves, manifolds, or pipe.
• Use thread sealant or PTFE tape as required by your system.

Typical Applications

• Connecting lay flat discharge hose to 3" trash pumps and transfer pumps.
• Temporary or seasonal setups where hoses are moved frequently between fields or locations.
• Dewatering, flood control, and other water-moving projects using lay flat hose.

Choosing the Right Camlock Type for Your System

Type B camlocks are usually used with a matching 3" male camlock adapter on the hose side. For a typical agricultural or pump setup you might combine:

• Type B 3" Aluminum Camlock (this fitting) on the pump or manifold (threaded side).
• Type E or C camlock with hose shank on the lay flat or suction hose end.
• A T-bolt clamp to secure the hose to the shank on lay flat hose.
