5/8′ Hex Nut for Keg Coupler
A 5/8′ Hex Nut typically attaches your keg coupling to your beer line, loose or damaged hex nuts can lead to leaks or disconnections.
Regularly checking your fittings and seals will allow you to keep your keg seals tight while also preventing leaks. For best results, we recommend that you check your keg seals/fittings every 4-6 months, and replace major seals/fittings once per year.
Stainless steel fittings are sturdier than plastic and will generally last you years at a time, but it is important not to become complacent. Check fittings often and replace damaged fittings as soon as possible.
