"A reasonable fitting that performed at installation as it should I have no reason to believe that the fitting will not out live the central heating system it is now attached too. Could be cheaper but it is competitively priced and brass fittings will always be affected by the value of the raw material. The parallel bsp thread was well cut and the whole fitting well machined. was supplied with a brass olive that gripped well once tweaked up. I used this fitting to attach a 3/4" bsp male thread on an expansion vessel to 15mm copper pipework on a central heating system to replace the failed internal expansion vessel in an aging combi boiler."
