发明名称 MALE THREADED PIPE FITTING EXTRACTION DEVICE
摘要 The present invention relates to tools or devices which are commonly used for extracting or removing damaged or broken male threaded pipe fittings from their female threaded fitting counterparts. Said damaged male pipe fittings are often removed or extracted as a cost savings measure, in order to salvage the female fitting portion. This avoids the necessity and cost of discarding and replacing both the damaged or broken male fitting, as well as the undamaged female fitting or fittings. This salvage process is especially cost effective in cases where the broken or damaged male pipe fitting in question, is part of a larger, more expensive plumbing assembly or system.
