ABSTRACT:
A male member to a hose adapter as for metal to metal, male to female, mating has a frustoconical sealing surface, for example, of 30, 37 or 45 degrees, for mating with a corresponding female member having a corresponding sealing surface. These surfaces are secured by a rotating female member, threads of which mate with the corresponding, threaded male member. The mating parts are drawn together as the threads are engaged and fully torqued. The male frustoconical surface is interrupted by a machined recess or undercut area, for example, of about 0.20 to 0.40 inches deep. This recess or undercut typically starts about one third of the way up the male frustoconical surface, and continues until the taper incline intersects with the threaded plane parallel to the bore of the adapter, and a recess or undercut extension can continue along the thread plane parallel or slightly tapered with respect to the bore until it reaches the base of the male thread, where it terminates. This machined space can then be taken up with a replaceable elastomer sealing boot.
