TUFFJ CAP SPOUT ADAPTER

Threaded adapter for the TUFF JUG Auto-Stop Spout, designed for small-diameter tank openings: late model vehicles (including capless fuel systems), chainsaws, lawn mowers and yard equipment.

Wide compatibility — fits any tank opening of at least 0.8" (20 mm) and works with all three TUFF JUG container sizes

Leak-proof seal — built-in Viton o-rings for a drip-free connection

Threaded fit — screws directly onto the Auto-Stop Spout, no tools needed

Heavy-duty construction — resistant to fuels and common fluids

Flow rate note — flow is reduced compared to the standard spout due to the narrower internal diameter and limited vent reach; installing an external poly vent significantly improves pour speed
