Profile: Shand Engineering Ltd. is a manufacturer of flow line connecting solutions for rubber hose and reinforced thermoplastic pipe. Our products include dry break couplings, swaging machines & tools, and swage fittings. Dry break couplings are used to prevent spillage of petro-chemicals during the connection and disconnection of flowlines. External swage fittings are inherently safer than clamp type fittings. Combo swage fittings are generally more economically priced than internal or external swaged fittings due to their simpler construction.
