Two-Sided Adaptor
Disclosed herein is an adaptor having a body having a first end and a second end opposed to the first end, the first end and the second end are made from dissimilar materials, the first end has an outer surface supporting a concentric barb for connecting to a tubing, and the second end has a receptacle for connecting to a fitting.
1 . An adaptor comprising:
a body having a first end and a second end opposed to the first end, the first end and the second end are made from dissimilar materials, the first end has an outer surface supporting a concentric barb for connecting to a tubing, and the second end has a receptacle for connecting to a fitting.
2 . The adaptor of claim 1 wherein the first end is dimensioned to connect to an internal lumen of the tubing.
3 . The adaptor of claim 2 wherein the receptacle is dimensioned to circumscribe a portion of an outer surface of the second tubing.
4 . The adaptor of claim 1 wherein the first end is made from a polymeric material having a modulus of elasticity greater than that of the second end.
5 . The adaptor of claim 1 wherein the first end is made from a material selected from the group consisting of: polyamides, polyesters, polyolefins, cyclic olefin copolymers, polysulfones, polyphenyl sulfides, and polyvinyl chlorides.
6 . The adaptor of claim 1 wherein the first end is made from an aliphatic polyamide, a semi-aromatic polyamide or an aromatic polyamide.
7 . The adaptor of claim 1 wherein the first end is made from nylon 6,6.
8 . The adaptor of claim 1 wherein the second end is made from a thermoplastic elastomer or a thermosetting elastomer.
9 . The adaptor of claim 8 wherein the thermoplastic elastomer is selected from the group consisting of: styrenic block copolymers, thermoplastic polyolefin elastomers, thermoplastic vulcanizates, thermoplastic urethanes, thermoplastic copolyesters, thermoplastic polyamides, and unclassified thermoplastic elastomers.
10 . The adaptor of claim 8 wherein the thermosetting elastomer is selected from the group consisting of: ethylene propylene diene monomer (EPDM), epichlorohydrin rubber, chloroprene, nitrile rubber, hydrogenated nitrile rubber, fluorinated rubber (FKM), polyacrylate rubber (ACM), ethylene acrylate rubber (AEM), styrene-butadiene-rubber (SBR), chloro-sulfonated monomer (CSM), and isoprene-isobutylene rubber.
11 . A method for connecting a first tubing to a second tubing comprising the steps of:
providing a body having a first end and a second end opposed to the first end, the first end and the second end are made from dissimilar materials, the first end has an outer surface supporting a concentric barb for connecting to the first tubing, and the second end has a receptacle for connecting to the second tubing;
inserting the first end into a lumen of the first tubing; and,
attaching the receptacle to a portion of an outer surface of the second tubing to establish a fluid flow connection between the first tubing and the second tubing.
12 . The method of claim 11 further comprising the step of mounting a hose clamp about the circumference of the second end.
13 . The method of claim 9 wherein the second end is removably connected to the second tubing.
14 . A method for making an adaptor comprising the steps of:
providing a substrate of a first material, the substrate having a first end and a second end, the first end has an annular flange and the second end has an outer surface supporting a concentric barb;
providing a first mold;
positioning the substrate adjacent to the first mold with a portion of the first end positioned inside the first mold;
injecting a molten second material different from the first material into the first mold to form a body having a third end and an opposed fourth end, the third end has a receptacle and the fourth end has an annular chamber; and,
ejecting the adaptor from the first mold.
15 . The method of claim 14 wherein the step of providing the substrate comprises the steps of providing a second mold, injecting the first material in a molten state under pressure into the second mold, ejecting the substrate from the second mold and allowing the substrate to cool.
16 . The method of claim 14 wherein the step of providing the substrate comprises the steps of providing a second mold, injecting the first material in a molten state under pressure into the second mold, and the step of positioning the substrate is performed while the substrate is hot.
17 . The method of claim 14 wherein the annular flange has a plurality of through holes and the second material is positioned in the through holes.
18 . The method of claim 14 further comprising the step of applying a primer to a portion of the substrate prior to injecting the second material into the first mold.
19 . The method of claim 14 further comprising the step of exposing a portion of the substrate to a plasma surface treatment prior to injecting the second material into the first mold.
20 . The method of claim 14 wherein the first material is more rigid than the second material.
