A straight SUS303 stainless hose end for -4 braided line terminating in a female AN4 connection. The -4 size is the usual step up when a -3 line is marginal on flow, so it is common on clutch hydraulics, turbo oil feeds, remote gauge plumbing and low-volume fluid transfer runs. The straight body keeps the finished assembly compact and gives the most direct flow, which is worth having when the whole reason for going to -4 was flow in the first place. Stainless construction stands up to fluid and weather. Match the seat form on the mating male AN4 fitting and check hose length allowing for the fitting’s own reach.
