Abstract

Claims (35)

1. A push fitting joint packing arrangement, comprising:

a fastening ring, wherein the fastening ring includes a substantially cylindrical-shaped support base having an interior and an exterior side, with the interior side having a single axial position and not multiple axial positions from which a plurality of teeth extend, and wherein the fastening ring has a diameter that exceeds the diameter of a split o-ring support member;

the split o-ring support member immediately adjacent the fastening ring; and

a spacer member integrally formed with the fastening ring to form a single monolithic member.

2. The arrangement of claim 1 , wherein the plurality of teeth have circumferential separations therebetween along the single axial position of the interior side of the support base.

3. The arrangement of claim 1 , wherein the split o-ring support member includes a first and a second circumferential end point that do not connect, wherein the first and second end points include facing edges, and wherein the facing edges are not aligned with respective radial axes of the support member.

4. The arrangement of claim 1 , further including at least one o-ring member.

5. The arrangement of claim 1 , further including a push release cap.

6. A method of enabling a fitting to receive a pipe through push connection, comprising:

providing a fitting;

inserting a split o-ring support member into the fitting;

providing a fastening ring with a spacer member integrally formed therewith to form a single monolithic member, wherein the fastening ring includes a substantially cylindrical-shaped support base having an interior and an exterior side, with the interior side having a single axial position and not multiple axial positions from which a plurality of teeth extend, and wherein the fastening ring has a diameter that exceeds the diameter of the split o-ring support member; and

inserting the fastening ring with integral spacer member into the fitting.

7. The method of claim 6 , wherein the plurality of teeth have circumferential separations therebetween along the single axial position of the interior side of the support base.

8. The method of claim 6 , wherein the split o-ring support member includes a first and a second circumferential end point that do not connect, wherein the first and second end points include facing edges, and wherein the facing edges are not aligned with respective radial axes of the support member.

9. The method of claim 6 , including the step of inserting at least one o-ring member into the fitting before inserting the o-ring support member.

10. The method of claim 6 , including the step of inserting a push release cap into the pipe fitting.

11. A push fitting joint packing arrangement, comprising:

a piping element having an inner wall;

at least one o-ring member maintained against the piping element inner wall, wherein the at least one o-ring member comprises a pair of o-ring members substantially abutting one another within the piping element;

a split o-ring support member immediately adjacent the o-ring member, with the support member having a radially outer surface engaging the piping element inner wall; and

a fastening ring immediately adjacent the split o-ring support member, wherein the fastening ring has a diameter that exceeds the diameter of the o-ring support member, wherein the fastening ring includes a substantially cylindrical-shaped support base having an interior and an exterior side, with the interior side having a single axial position and not multiple axial positions from which a plurality of teeth extend.

12. The arrangement of claim 11 , wherein the plurality of teeth have circumferential separations therebetween along the single axial position of the interior side of the support base.

13. The arrangement of claim 11 , wherein the split o-ring support member includes a first and a second circumferential end point that do not connect, wherein the first and second end points include facing edges, and wherein the facing edges are not aligned with respective radial axes of the support member.

14. A push fitting joint packing arrangement, comprising:

a fastening ring, wherein the fastening ring includes a substantially cylindrical-shaped support base having an interior and an exterior side, with the interior side having a single axial position and not multiple axial positions from which a plurality of teeth extend;

a split o-ring support member immediately adjacent the fastening ring;

a spacer member integrally formed with the fastening ring to form a single monolithic member; and

a push release cap.

15. A method of enabling a fitting to receive a pipe through push connection, comprising:

providing a fitting;

inserting a split o-ring support member into the fitting;

providing a fastening ring with a spacer member integrally formed therewith to form a single monolithic member, wherein the fastening ring includes a substantially cylindrical-shaped support base having an interior and an exterior side, with the interior side having a single axial position and not multiple axial positions from which a plurality of teeth extend;

inserting the fastening ring with integral spacer member into the fitting; and

inserting a push release cap into the pipe fitting.
