Dixon Valve & Coupling Co. 3020-B-AL Cam and Groove Coupling

SKU CH-K9K0-EM01W

Aluminium cam-and-groove coupling connects 2 in MNPT thread to 3 in hose, rated 125 psi at 70 °F with nitrile gasket and locking arm

  • Aluminium body resists corrosion for longer service life
  • Type B socket accepts 2 in MNPT threaded connections
  • Nitrile gasket seals reliably at 125 psi working pressure
  • Locking arm included secures coupling during operation
  • Rated for 70 F maximum working temperature

3 in Type B Aluminium Cam and Groove Coupling

This Dixon cam and groove coupling connects a 2 in male NPT thread to a 3 in hose fitting. The aluminium body and nitrile gasket suit fluid transfer in industrial and agricultural plumbing systems.

Upgrade from smaller or non-locking fittings

Replacing a 2 in coupling with this 3 in socket increases flow capacity for high-volume lines. The integrated locking arm adds secure retention that basic cam arms lack, making the change worthwhile when vibration or pressure spikes risk accidental disconnection.

Sustained pressure performance at 70 F

The coupling is rated for 125 psi maximum working pressure at 70 F, so it maintains seal integrity during continuous pump operation. Aluminium construction resists corrosion in water-based media, while the nitrile gasket retains elasticity over long duty cycles without hardening.

Questions about this item

Will the 2 in NPT male thread on this 3 in Type B socket connect directly to my 2 in NPT female port?

Yes, the coupling has a 2 in -11-1/2 NPT male thread that mates with a standard 2 in NPT female connection.

Do I need thread sealant or a gasket when installing the 2 in NPT male end, and which step is commonly missed?

Apply PTFE tape or pipe dope to the NPT threads; the Nitrile gasket inside the 3 in cam socket seals the hose side separately.

How often should I replace the Nitrile gasket inside the 3 in cam socket under normal 125 psi service at 70 F?

Inspect the Nitrile gasket each time you disconnect; replace it once it shows cracks, hardening or permanent compression set.
