All Ark-Plas Premium Grade Fittings are molded with the company’s “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 a 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. Material certification can be supplied upon request.
The line of Premium Grade Fittings are 100% quality inspected before being packaged and shipped to customers. Premium Grade Fittings are meticulously molded under controlled conditions, and are inspected for even the slightest quality defect by trained personnel wearing protective gloves to avoid the possibility of product contamination.
Designed for ease of use, Premium Grade Fittings with standard barbs have an easy-to-hold base, and a barb 1.4 to 1.5 times larger (depending on size of fitting) than the tubing ID. Once the single sharp-barb is inserted into the tubing, a secure, leak-proof seal is formed that can hold up to 125 psi without the use of clamps or ties.
Premium Grade Fittings with “hard-line” barbs are designed for use with semi-rigid tubing to provide a leak-proof seal without the use of cable clamps. When inserted, the barb’s sharp, the trailing edge digs into the tubing, creating a bond that can hold up to 200 psi.
