Ham-Let Let-Lok tube fittings are strictly standardised and designed for high performance in the most demanding industrial applications. The fittings are designed to resist corrosive environments, have exceptional tensile strength, withstand long term vibration and perform to specifications under a wide range of extreme temperatures and pres-sures. The range of compression tube fittings offer simple leak-free connection and reliable installation over a range of field conditions. These fittings are manufactured to the highest quality standards and can withstand four times the max. allowable pressure of a selected tube per ASTM A-269/213. They can be used with a wide variety of tubing materials and a broad range of tube wall thicknesses, while showing high durability and consistency in performance.
