Abstract

A tube fitting includes a multi-way tube member and a coupler. The multi-way tube member includes three interconnected tube-connecting segments, one of which has two locking portions disposed at a distal end thereof. The coupler includes a cap section covering one of the tube-connecting segments having the locking portions, two resilient retaining portions snapped respectively to the locking portions, a guide tube section extending from the cap section into the one of the tube-connecting segments, and a connecting tube section extending from the cap section in a direction away from the guide tube section for connection with an additional coupler. A curable filler can be filled among the multi-way tube member, the coupler, and a tube for fixing the tube within the multi-way tube member.

Dependent claims

A tube fitting adapted to be connected to a tube, said tube fitting comprising:

a multi-way tube member including three tube-connecting segments in fluid communication with each other and each having a distal end formed with an end opening, said distal end of at least one of said tube-connecting segments having two locking portions and at least one overflow notch;
and
a coupler mounted removably to and in fluid communication with one of said tube-connecting segments having said locking portions and including a cap section covering said distal end of said one of said tube-connecting segments, two spaced-apart resilient retaining portions extending from said cap section and permitting said locking portions to be snapped respectively thereto so as to position said cap section relative to said one of said tube-connecting segments, a guide tube section that extends from said cap section into said one of said tube-connecting segments to guide said distal end of said one of said tube-connecting segments into a space between said resilient retaining portions and that is adapted to connect with one of the tubes extending into said one of said tube-connecting segments to retain said one of the tubes thereon, and a connecting tube section extending from said cap section in a direction away from said guide tube section and adapted for connection with an additional coupler, said cap section being formed with a connecting hole in spatial communication with said guide tube section and said connecting tube section.

A tube fitting set comprising:

two multi-way tube members, each of said multi-way tube members including three tube-connecting segments in fluid communication with each other and each having a distal end formed with an end opening, said distal end of at least one of said tube-connecting segments of each of said multi-way tube members having two locking portions and at least one overflow notch;
and
two couplers each mounted removably to and in fluid communication with one of said tube-connecting segments of a corresponding one of said multi-way tube members having said locking portions and including a cap section covering said distal end of said one of said tube-connecting segments, two spaced-apart resilient retaining portions extending from said cap section and permitting said locking portions to be snapped respectively thereto so as to position said cap section relative to said one of said tube-connecting segments, a guide tube section that extends from said cap section into said one of said tube-connecting segments to guide said distal end of said one of said tube-connecting segments into a space between said resilient retaining portions and that is adapted to connect with one of the tubes extending into said one of said tube-connecting segments to retain said one of the tubes thereon, a connecting tube section extending from said cap section in a direction away from said guide tube section and adapted for connection with the other of said couplers, and a connecting hole formed through said cap section and in spatial communication with said guide tube section and said connecting tube section, said connecting tube section of one of said couplers having an internally threaded portion, said connecting tube section of the other of said couplers having an externally threaded portion engaging said internally threaded portion, so that said couplers are interconnected removably.

A tube fitting set comprising:

two multi-way tube members, each of said multi-way tube members including three tube-connecting segments in fluid communication with each other and each having a distal end formed with an end opening, said distal end of at least one of said tube-connecting segments of each of said multi-way tube members having two locking portions and at least one overflow notch;
two couplers each mounted removably to and in fluid communication with one of said tube-connecting segments of a corresponding one of said multi-way tube members having said locking portions and including a cap section covering said distal end of said one of said tube-connecting segments, two spaced-apart resilient retaining portions extending from said cap section and permitting said locking portions to be snapped respectively thereto so as to position said cap section relative to said one of said tube-connecting segments, a guide tube section that extends from said cap section into said one of said tube-connecting segments to guide said cap section to be sleeved on said distal end of said one of said tube-connecting segments and that is adapted to connect with one of the tubes extending into said one of said tube-connecting segments to retain said one of the tubes thereon, a connecting tube section extending from said cap section in a direction away from said guide tube section and adapted for connection with the other of said couplers, and a connecting hole formed through said cap section and in spatial communication with said guide tube section and said connecting tube section, said connecting tube section of one of said couplers having an internally threaded portion, said connecting tube section of the other of said couplers having an externally threaded portion engaging said internally threaded portion, so that said connecting tube sections of said couplers being interconnected removably;
and
at least one clamp disposed between and clamping removably said multi-way tube members.
