3/8” mini straight ball valve 1/4-turn feature prevents leaking supply stops. Chrome plated, heavy brass construction provides years of reliable service. A washerless design with hi-temp Viton seats results in replacing less often than conventional stops. The retrofit style creates a new stop by “piggybacking” onto existing defective 3/8” OD compression angle stops, straight stops or adapters without effecting the existing piping. 3/8” NPT F x F.
