Coupling with guide is our new products, which is designed to avoid the direct abrasion between coupling and tubing. We use the molded machine to press guide on different sizes of couplings, as the guide material is tender nylon or PPA, so the abrasion is between guide and tubing, which is soft so as to protect both coupling and tubing. Our guide is high plasticity and high temperature resistance, so it can enhance your well productivity and long time working life.
