What's a good HIGH TEMPERATURE connection?
Hoke Gyrolok tube fittings hold their own when the heat is on. Furthermore, the seal holds as temperature cycles up & down. Even if you don't run into 1500° temperatures, the variety of sizes, shapes & materials in the brand new Gyrolok catalog will save you time & energy. (Your Hoke distributor has catalogs, fittings & information in stock. Call him . . . or us. See us at BOOTH 635, Plant Engineering & Maintenance Show, Convention Hall, Philadelphia, Pa. March 25-28
