The MARK UNION has MADE GOOD in every marine installa- tion, 1901 Dempster Street MARK MANUFACTURING CO. Being made of the same material as the piping, the Mark Union expands and contracts in the same ratio as the piping. The Mark Union resists the corrosive action of sea water and salt air because all parts, including the threads, are protected by a rust-proof coating. It is designed to carry high pressure as well as low pressure and all sizes are equally strong. Write for sample. EVANSTON, ILL, Please mention Tue Marine Review when writing to Advertisers
