Abstract

A pass-through bulkhead seal fitting for use in the aircraft industry is disclosed. In one example, a pass-through bulkhead seal fitting includes a male fitting comprising a tubular body that is separable to receive existing wiring, and a nut that is separable to receive existing wiring and being rotatable in a single direction relative to a longitudinal axis of the male fitting.

First claim

What is claimed is:

1. A pass-through bulkhead seal fitting, comprising:
a male fitting comprising a tubular body having a first portion and a second portion that are separable from one another to receive existing wiring, wherein each of the first portion and the second portion of the tubular body comprises a plurality of sealant exit ports that extend from an inner surface of the respective first and second portions of the tubular body to an outer surface of the respective first and second portions of the tubular body; and
a nut having a first nut portion and a second nut portion that are separable from one another to receive existing wiring, the nut being rotatable in a single direction relative to a longitudinal axis of the male fitting.

2. The fitting of claim 1 , wherein the plurality of sealant exit ports are located at a first end of the respective first and second portions of the tubular body.

3. The fitting of claim 2 , wherein each portion of the tubular body includes a second end opposing the first end that includes a plurality of raised features on the outer surface thereof.

4. The fitting of claim 3 , wherein the plurality of raised features are oriented along the longitudinal axis of the male fitting.

5. A pass-through bulkhead seal fitting, comprising:
a male fitting comprising a tubular body having a first portion and a second portion that are separable from one another to receive existing wiring, the tubular body comprising a flange extending in a radial direction from an outer surface thereof, the flange including a channel that is in fluid communication with an inner surface of the tubular body; and
a nut having a first nut portion and a second nut portion that are separable from one another to receive existing wiring, the nut being rotatable in a single direction relative to a longitudinal axis of the male fitting.

6. The fitting of claim 5 , wherein the flange includes one or more openings for determining a sealant level within the channel.

7. A pass-through bulkhead seal fitting, comprising:
a male portion comprising a tubular body having a first portion and a second portion each extending a longitudinal length of the tubular body, the first portion and the second portion defining a volume within the tubular body and separable from one another, the tubular body having a plurality of sealant exit ports located in a radial direction relative to a longitudinal axis of the male portion through an inner surface of the tubular body to an outer surface of the tubular body, the plurality of sealant exit ports in fluid communication with the volume; and
a nut separable into a first nut portion and a second nut portion, the nut being rotatable in a single direction relative to the longitudinal axis of the male portion.

8. The fitting of claim 7 , wherein the plurality of sealant exit ports are formed at a first end of the tubular body.

9. A pass-through bulkhead seal fitting, comprising:
a male portion comprising a tubular body having a first portion and a second portion separable from one another, the tubular body having:
a plurality of sealant exit ports located in a radial direction relative to a longitudinal axis of the male portion through an inner surface of the tubular body to an outer surface of the tubular body, and
a second end opposing the first end that includes a plurality of raised features formed in the outer surface thereof; and

a nut separable into a first nut portion and a second nut portion, the nut being rotatable in a single direction relative to the longitudinal axis of the male portion, wherein the nut includes a detent that interfaces with the raised features to prevent the nut from rotating in a direction other than the single direction.

10. A pass-through bulkhead seal fitting, comprising:
a male portion comprising a tubular body having a first portion and a second portion each extending a longitudinal length of the tubular body, the first portion and the second portion defining a volume therein, the first portion and the second portion separable from one another, wherein the male portion comprises a first end having a plurality of sealant exit ports and a second end opposing the first end; and
a nut separable into a first nut portion and a second nut portion, the nut being rotatable in a first direction relative to a longitudinal axis of the male portion and having one or more detents formed thereon that prevents rotation of the nut in a second direction opposite to the first direction.

11. The fitting of claim 10 , wherein the second end includes an outer peripheral surface having a plurality of raised features formed thereon that interface with the one or more detents.

12. The fitting of claim 10 , wherein each portion of the tubular body includes an interlock device securing the tubular body.

13. A pass-through bulkhead seal fitting, comprising:
a male portion comprising a tubular body having a first portion and a second portion each extending a longitudinal length of the tubular body, the first portion and the second portion defining a volume therein, the first portion and the second portion separable from one another, wherein each portion of the tubular body comprises a flange extending in a radial direction from an outer surface thereof and each flange includes a channel that is in fluid communication with an inner surface of the tubular body; and
a nut separable into a first nut portion and a second nut portion, the nut being rotatable in a first direction relative to a longitudinal axis of the male portion and having one or more detents formed thereon that prevents rotation of the nut in a second direction opposite to the first direction.
