Hose Couplers

Hose couplers create connection points between hoses, tubing, pumps, and threaded components in commercial water-transfer and liquid-handling setups. This category includes camlock couplers and adapters, hose-shank couplings, coupling sets, king nipples, and dust plugs for water pumps, suction and discharge hose, and hoses used to handle water and other liquids.

Helpful Buying Guide

Choose hose couplers for compatible pump and hose connections

The fittings represented here support a range of pump, hose, and fluid-handling connection arrangements. Start by matching the connection size, then identify the needed end style—such as a camlock coupler, threaded end, hose shank, or closure plug—and confirm the material and installation requirements for the assembly.

Use Cases

Build pump and hose connections

Use camlock couplers and threaded fittings to connect compatible hoses or tubing to water pumps. Cam and groove adapters are represented for suction and discharge hose arrangements.

How to Choose

Match size and connection ends

Compare the stated size with the compatible connection requirement, then select the required configuration, such as MPT, FPT, male NPT, male barb, hose shank, or male and female coupling components.

Applications

Support water and liquid handling

Represented applications include water-pump setups, transfer pumps, suction and discharge hose, and hoses used to move water and other liquids.

Additional Info

Plan for installation details

Some short-shank couplings and king nipples require clamps for hose attachment. Dust plugs are represented for closing compatible intake or outlet openings when equipment is not in use.

Planning Guide

Plan the right fit before choosing

Connection types

Select the fitting style your assembly requires

Camlock male couplers are available with threaded ends in MPT or FPT configurations, while certain adapters pair cam and groove connections with male NPT ends or hose shanks. Other represented options include a male barb to male coupler thread fitting, male IPT short-shank coupling, and a matching male and female short-shank coupling set.

  • Camlock male couplers with MPT or FPT threaded ends
  • Cam and groove adapters with male NPT or hose-shank connections
  • Short-shank couplings, a king nipple, and a male barb configuration
Size and material

Match dimensions and choose the stated material

The represented selection includes 1 inch, 1-1/2 inch, 2 inch, and 3 inch connection sizes. Aluminum is common across couplers and adapters, while polypropylene options include camlock fittings and a female cam-and-groove adapter. A plated steel king nipple and a coupling set with a brass pin-lug nut are also represented.

  • 1 inch and 1-1/2 inch camlock couplers
  • 2 inch coupling, adapter, and dust-plug options
  • 3 inch couplers, adapters, and a plated steel king nipple
Installation and maintenance

Account for clamps and closure needs

For hose-shank and related hose-tube connections, review whether clamps are required before completing the assembly. The listed short-shank couplings and king nipple require clamps for hose attachment. For idle equipment, a compatible camlock dust plug can close an intake or outlet opening to help limit leaks and keep debris from entering equipment.

  • Use required clamps with compatible short-shank couplings and king nipples
  • Consider a coupling set when matching male and female components are needed
  • Use a compatible dust plug to close unused pump or hose openings
FAQ

Common questions before buying
