Abstract
A fluid coupling having an outer housing with an internal bore, an O-ring fitted within the bore, a spacer bushing fitted against the O-ring, a gripper ring fitted against the axially outer side of the spacer ring, the gripper ring having axially and radially inwardly protruding circumferentially spaced gripping teeth, and an end bushing holding the gripper ring, spacer bushing, and O-ring within the outer housing. A second gripper ring and a second spacer ring are used in some embodiments.
Claims19
A coupling for holding a tube therein, comprising:
- an outer housing having an internal bore with a circumferential side wall,
- a seal retained against axial movement within said internal bore in fluid-tight engagement with said housing and positioned for fluid-tight engagement with the tube when positioned within said internal bore,
- a non-movable first spacer bushing retained against axial movement within said internal bore and having an axially inner side and an axially outer side,
- a non-movable second spacer bushing retained against axial movement within said internal bore and having an axially inner side and an axially outer side,
- a first gripper ring located axially outward of said seal and having a non-movable peripheral portion retained against axial movement within said internal bore, said first gripper ring further including gripper teeth extending inwardly from said peripheral portion of said first gripper ring and positioning inner edges of said gripper teeth stationary within said internal bore in position awaiting engagement with the tube when positioned within said internal bore without adjusting movement of said first gripper ring, said peripheral portion of said first gripper ring lying adjacent and between said axially outer side of said first spacer bushing and said axially inner side of said second spacer bushing, and
- a second gripper ring located axially outward of said second spacer bushing and having a non-movable peripheral portion retained against axial movement within said internal bore, said second gripper ring further including gripper teeth extending inwardly from said peripheral portion of said second gripper ring and positioning inner edges of said gripper teeth stationary within said internal bore in position awaiting engagement with the tube when positioned within said internal bore without adjusting movement of said second gripper ring, said peripheral portion of said second gripper ring lying adjacent said axially outer side of said second spacer bushing.

A coupling for holding a tube therein, comprising:
- an outer housing having an internal bore with a circumferential side wall, said internal bore being sized to receive the tube therein,
- a non-movable first spacer bushing retained against axial movement within said internal bore and having an axially inner side and an axially outer side,
- a non-movable second spacer bushing retained against axial movement within said internal bore and having an axially inner side and an axially outer side,
- a first gripper ring having a non-movable peripheral portion retained against axial movement within said internal bore, said first gripper ring further including gripper teeth extending inwardly from said peripheral portion of said first gripper ring and positioning inner edges of said gripper teeth stationary within said internal bore in position awaiting engagement with the tube when positioned within said internal bore without adjusting movement of said first gripper ring, said peripheral portion of said first gripper ring lying adjacent and between said axially outer side of said first spacer bushing and said axially inner side of said second spacer bushing, and
- a second gripper ring having a non-movable peripheral portion retained against axial movement within said internal bore, said second gripper ring further including gripper teeth extending inwardly from said peripheral portion of said second gripper ring and positioning inner edges of said gripper teeth stationary within said internal bore in position awaiting engagement with the tube when positioned within said internal bore without adjusting movement of said second gripper ring, said peripheral portion of said second gripper ring lying adjacent said axially outer side of said second spacer bushing.
