Our Commercial Grade Fittings are molded for ease of use in application. No special tools or ferrules are required for fitting insertion. Ark-Plas® Commercial Grade Fittings fit the need when a low cost, high performance fitting is required that is both cost efficient and reliable. With high quality standards applied, our Commercial Grade Fittings provide a leak-proof seal with pressure up to 125 P. S. I. without the use of clamps or ties. The FA and FB item numbers are very similar. To view the difference, you will need to open the engineering drawing for both items. Commercial Grade Fittings are stocked in our standard materials: Nylon and Polypropylene. Other material options include Black Heat-Stabilized Nylon, Black High-Density Polyethylene, White High-Density Polyethylene, Polycarbonate, Kynar®, and Acetal. Fittings molded with non-standard materials may not fall within Ark-Plas® standard tolerances due to variation from standard materials in shrinkage properties. A 5,000 piece minimum order is required for non-standard materials.
