Use a brass hose coupling when you need to insert a thermocouple or pressure transducer in a fluid or coolant line. Available OD sizes range from 1/2 inch to 2-1/2” inch with either one or dual 1/8” inch FNPT ports. Simply cut the hose, insert Temprel’s Brass Hose Coupling and secure with 2 hose clamps on both sides. For simple repairs, a bridge tube is available without the 1/8” inch fitting for a secure leak-free connection. Please contact Temprel for pricing and bridge tube information. Custom and metric sizes are also available.
