COUPLING FOR FLUID LINE ASSEMBLY
FIG2 is a side cross-sectional view of the fluid line assembly of FIG1, in accordance with an embodiment of the present disclosure 
A coupling between the second coupler 132 and the first coupler 130 may define a joint 290 therebetween. For facilitating fluid transmission through the passage 118, the first axial end face 162 and the second axial end face 240 may meet, and/or may contact each other at the joint 290. As may be noted in an enlarged callout 310 for the joint 290 in FIG2, a clearance between the first axial end face 162 and the second axial end face 240 is generally exaggerated. Such exaggeration is solely to assist with identifying the different portions and/or elements disposed close to the joint 290, as is discussed in the present disclosure. It may be appreciated that in an actual practice, and upon establishing the assembly between the first coupler 130 and the second coupler 132, such an exaggerated clearance may be non-existent.

['1. A coupling (114) for a fluid line assembly (100) including a first fluid line (110) and a second fluid line (112), the coupling (114) comprising: a first coupler (130) adapted to be connected to the first fluid line (110), and including a first axial end face (162) with a groove (168); a second coupler (132) adapted to be connected to the second fluid line (112), and being couplable with the first coupler (130) to combinedly define a passage (118) therethrough for fluidly connecting the first fluid line (110) with the second fluid line (112), the second coupler (132) including a second axial end face (240) with a channel (246), the second axial end face (240) being contactable with the first axial end face (162); a seal (134) at least partly received within the groove (168) and adapted to abut the second axial end face (240) of the second coupler (132) to prevent a leakage of fluid from the passage (118); and a friction member (136) at least partly received within the channel (246) and adapted to engage the first axial end face (162) of the first coupler (130) to restrict a torsional movement between the first coupler (130) and the second coupler (132).', '4. The coupling (114) of claim 1 further including a locking nut (138) for securing the first coupler (130) with the second coupler (132).', '8. The coupling (114) of claim 1, wherein the first axial end face (162) includes a first planar surface (184), the friction member (136) including a friction surface (306) to contact the first planar surface (184).', '9. The coupling (114) of claim 1, wherein the second axial end face (240) includes a second planar surface (258), the seal (134) including a sealing surface (294) to contact the second planar surface (258).']
