LinkTech 10AC couplings are produced in a durable natural Acetal thermoplastic. The Acetal couplings are resistant to most mild chemicals and are manufactured to be trouble free for many years of service. They are intuitive to use and make an audible click when coupled with their new and improved “Easy Grip Barrel.” The 10AC couplings interconnect with each other as well as other similar industry twist lock type couplings.
