All Ark-Plas® Plastic Premium Grade Fittings are molded with our ”Premium Grade” technology. This means that every sealing surface on each barb is seamless all the way around, due to the lack of a parting line, eliminating flash or mold mismatch. Coupled with our high-quality manufacturing processes, ”premium grade” technology helps to ensure a leak-proof seal with each use.
Premium Grade Fittings are molded from 100% virgin material only. Material certification can be supplied upon request. Because of strict quality control standards imposed on our Premium Grade Fittings, no returns can be accepted for any reason other than error by Ark-Plas®. This is your guarantee that no fittings ever leave our control, only to be restocked for future sale. This allows only the highest quality fittings to be marked as Premium Grade Fittings.
