Aqualine GCAP-250 Threaded Galvanized Cap 2.5 Inches Order Now

The AQUALINE GCAP-250 is a 2.5-inch threaded galvanized steel pipe cap used to close off the end of a threaded pipe run in plumbing, irrigation, or industrial piping systems. The galvanized finish provides corrosion resistance, making it suitable for both indoor and outdoor installations where moisture exposure is a factor. This fitting is installed by licensed plumbers and pipefitters in residential, commercial, and light industrial applications. The internal threads accept standard NPT pipe ends, providing a secure, leak-resistant termination point on any compatible threaded pipe.

This cap is commonly used to plug the end of a galvanized steel pipe in water supply lines, irrigation mainlines, pool and spa equipment connections, and general-purpose plumbing rough-in work. It is appropriate for above-ground and underground installations where a permanent or temporary pipe termination is needed. Pool and irrigation service professionals frequently use caps like this to isolate sections of piping during system maintenance or winterization.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off the water supply and depressurize the line before threading the cap onto the pipe end. Apply appropriate thread sealant tape or compound to the male pipe threads before installation per local plumbing code requirements. Tighten with a pipe wrench to ensure a leak-free seal without overtightening, which can crack fittings or strip threads.
