KK18 Internal Coupling


An internal spigot providing a flush joint between two pipes of the same diameter. Not as strong as KK14 and must not be used where a direct tensile load is applied. This fitting can only be used with Schedule 40 steel pipe. Danger: KK18 fitting must not be used as a load bearing joint.
