Practical tips for installation
Ensure threads are clean and free of debris before installation. For a more reliable seal on metal threads, apply an appropriate thread sealant rated for metal piping, then hand-tighten the cap and finish with a light wrench turn—monitor for snug, not over-torqued, to prevent thread damage. Remember, these are female-threaded ends, so you’ll pair them with corresponding male 1/4" fittings.
