Buying Guide

Hose construction and material

Choose between rubber OEM-style hoses for flexibility and stainless-braided or nylon-braided hoses for abrasion resistance and higher temperature tolerance

Inner diameter and AN sizing

Match the hose ID or AN size (for example AN-6/8) to your vehicle’s fittings to ensure proper flow and leak-free connections

Length and included fittings

Measure run length before purchase and prefer kits or hoses that list lengths (like 10–20 ft options) or come with compatible fittings to avoid extra adapters

Compatibility with transmission types

Verify compatibility for specific transmissions (e.g., GM 4L60E/4L80E) and check whether assemblies are intended for oil cooler, radiator, or remote cooler hookups

Temperature and chemical resistance

Look for hoses rated for transmission fluid and high temperatures; braided covers and reinforced cores typically improve chemical and heat resistance
