Abstract
A hose end coupling comprising a unitary one-piece stem having an exterior barb end portion and an exterior ferrule interface portion, with a unitary one-piece radially crushable ferrule disposed over the stein, with a crushable socket portion disposed about the barb end portion, a deformable attachment portion disposed about the ferrule interface portion, and a torque communication portion defined between the socket portion and the attachment portion. The socket portion may retain a “C” shaped insert, one or more coiled inserts, or a plurality of stacked inserts, for gripping a hose end and the socket portion might define a lip, with a seal disposed in the socket portion between the insert(s) and the lip. Some embodiments of a “C” shaped insert define inner-circumferential teeth and corresponding outer-circumferential depression indentions.
