A fitting comprises a body with a generally flat first face, a gland with a generally flat second face, and a collet assembly adapted to be squeezed onto the outside of the conduit. A nut surrounds the gland and is adapted to engage the body, to force the first and second faces into sealing engagement with each other and to force the collet assembly into sealing engagement with a conduit and with an internal passage in the gland. When the nut is an advanced position, it engages the body, transmitting an axially compressive force to the first collet and pressing the forward end face of the gland against the rear end face of the body. When the nut is a retracted position, it has its forward end face no farther forward than the plane of the forward end face of the gland.
