3" PART DC, TOUGH-TITE ALUMINUM

APG stocks the 3E30DCAL, a Tough-Tite Aluminum Dust Cap Cam and Groove Coupling measuring a 3 inch nominal size. A cam and groove coupling closes off a female coupler to keep debris and moisture out of an idle line. The catalog record notes: Dust Cap.

The material holds up against general atmospheric corrosion, weathering, and many petroleum products. That behavior comes from the compound itself: Aluminum is specified for reduced operator fatigue on frequent connection cycles and a high strength-to-weight ratio that eases handling of large sizes. Verify compatibility before use with galvanic pairing with dissimilar metals or strong acids and alkalis.

Maintenance and OEM teams specify it across agriculture and irrigation, petroleum transfer, and construction and dewatering.

Order part number 3E30DCAL, sold individually. Unit weight is approximately 821 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
