COUPLING FOR FLUID LINE ASSEMLY

Abstract:

A coupling includes a first coupler, a second coupler, a seal, and a friction member. The first coupler is connectable to a first fluid line, and includes a first axial end face with a groove. The second coupler is connectable to a second fluid line, and is couplable with the first coupler to define a passage therethrough. The second coupler includes a second axial end face with a channel. The second axial end face is contactable with the first axial end face. The seal is received within the groove and is adapted to abut the second axial end face of the second coupler to prevent a leakage of fluid from the passage. The friction member is received within the channel and is adapted to engage the first axial end face of the first coupler to restrict a torsional movement between the first coupler and the second coupler.
