Abstract
A joint construction includes first and second conduit sections having coaxially overlapping end areas. A coupling member has a first end received within the end of the first conduit section and a second end with external threads. A bore of the coupling member receives the second section end area. A plurality of protrusions are formed on an outer surface of the coupling member. The plurality of protrusions engage a plurality of complimentary features formed on the end area of the first conduit section. A gland nut has threads configured to engage the external threads of the second end of the coupling member. A washer is disposed on the second conduit section between the second end of the coupling member and the gland nut. The washer is configured to engage the end area of the second conduit section to resist relative axial movement between the first and second conduit sections.
