Aqualine BCA-100 Threaded Brass Cap 1 Inch Best Seller

The AQUALINE BCA-100 is a 1-inch threaded brass cap designed to seal pipe ends in plumbing, irrigation, and water distribution systems. Machined from solid brass, this cap threads directly onto male-threaded pipe ends to provide a secure, leak-resistant closure. It is a compact, durable fitting suited for residential and light commercial applications where a reliable, permanent or temporary pipe termination is needed. Licensed plumbers and experienced pipe mechanics are the typical installers, though knowledgeable trades across HVAC and pool systems also use threaded brass caps for pressure testing and service isolation work.

The BCA-100 is appropriate for use in potable water lines, irrigation supply runs, pool and spa plumbing, and general hydronic piping where a 1-inch female-threaded termination is required. Its brass construction resists corrosion in wet environments, making it well suited for both indoor and outdoor installations. This cap is a practical choice any time a pipe end must be sealed during construction, service, or system modification.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before threading the cap onto the pipe end. Apply thread sealant tape or pipe dope to the male threads before installation to ensure a leak-free seal. Tighten by hand first, then use a pipe wrench to bring the cap to a snug fit without overtightening, which can crack the fitting or damage threads.
