Dixon Valve & Coupling Co. 1520-AA-AL Spool Adapter 1-1/2x2 In Male Adapter

Dixon 1520-AA-AL Spool Adapter

This aluminum Cam and Groove spool adapter connects a 1-1/2 inch male coupling to a 2 inch male coupling. It is designed for fluid-transfer systems that require a straight-through connection between two male ends. The adapter suits industrial and agricultural plumbing where dissimilar coupling sizes must be joined. Buyers who need a female thread or a different coupling standard will not find it here.

Sustained pressure performance

The fitting carries a maximum working pressure of 250 psi at 70 °F, so it holds seal integrity during continuous pumping or gravity-fed flow. Its locking-arm feature keeps the cam arms engaged under vibration or pressure cycling. The aluminum body resists corrosion from water and many chemicals, maintaining the pressure rating over long service intervals. Systems that exceed 250 psi or operate at higher temperatures require a different rating.

Thermal and installation profile

Aluminum construction keeps the adapter light at 3 9/16 inches overall length, reducing stress on connected hose or pipe runs. No moving seals or lubricated surfaces mean there is no noise generated during flow. The material dissipates heat quickly, so the fitting stays near ambient fluid temperature in normal use. Installers who need a heavier brass or stainless version for abrasive media should select another material.
