Disc Assembly, Part No. D41-8-05P, NSN 15760 — Worldwide Buyer's Guide to Partially Insulated Piggyback Disconnects
Table of Contentsexpand_more
Disc Assembly, Part No. D41-8-05P, NSN 15760 is a partially insulated piggyback disconnect — a socket/tab quick-connect terminal with a 0.25 in x 0.032 in tab that lets a second wire stack onto the same tab. It is used in control panels, appliances, and industrial machinery where fast wire termination and daisy-chaining are required.
What is a Disc Assembly, Part No. D41-8-05P, NSN 15760?
A Disc Assembly, Part No. D41-8-05P, NSN 15760 is a partially insulated piggyback disconnect: a crimp-style terminal with a male tab on one side and a female socket on the other, allowing two connections on a single point. The 0.25 in x 0.032 in tab matches standard quick-disconnect receptacles.
Piggyback disconnects are commonly supplied under brands such as 3M, STA-KON, BURNDY, and PANDUIT. The NSN 15760 reference indicates a national stock number classification used by defence and government procurement, which is why Worldwide buyers often search by both part number and NSN.
How does a piggyback disconnect work?
The terminal crimps onto a stripped wire via a butted barrel and seam construction. The male tab then plugs into a mating female receptacle, while the piggyback socket on top accepts a second terminal — enabling daisy-chaining without a separate junction block.
Partial insulation covers the barrel but leaves the tab exposed, so the connection can be inspected and re-terminated quickly. This is why the design is favoured in control cabinets, appliances, and industrial equipment where service access matters.
Spec table: key measurable attributes
| Attribute | Value |
|---|---|
| Tab size | 0.25 in x 0.032 in |
| Insulation type | Partial coverage (nylon or vinyl) |
| Barrel construction | Butted barrel and seam |
| Colour code | Red or yellow |
| Connection configuration | Socket/tab (piggyback) |
| Typical application | Control panels, appliances, industrial machinery |
Which piggyback disconnect type suits your application?
Red variants are typically used for smaller wire gauges, while yellow variants suit larger gauges — always confirm against your wire size and the OEM's colour code chart. Nylon insulation offers higher temperature and abrasion resistance than vinyl, which matters in control cabinets and machinery with heat exposure.
Vinyl insulation is a cost-effective choice for general-purpose panel wiring and appliances. If your application involves repeated mating cycles or vibration, nylon is the more durable option.
Selection criteria
- Tab size: confirm 0.25 in x 0.032 in matches your mating receptacle.
- Wire gauge: match the colour code (red vs yellow) to your conductor size.
- Insulation material: nylon for heat/abrasion resistance; vinyl for general-purpose use.
- Connection count: piggyback socket/tab allows stacking multiple connections on one tab.
- Environment: consider temperature, vibration, and exposure in control panels or machinery.
- Compliance: verify NSN 15760 cross-reference and any defence or export documentation requirements.
Product comparison ladder
| Model | Insulation | Colour | Tab size | Best for |
|---|---|---|---|---|
| Red Vinyl Partially Insulated Piggyback Disconnect | Vinyl, partial | Red | 0.25 in x 0.032 in | General panel wiring |
| Red Vinyl Partially Insulated Piggyback Disconnect | Vinyl, partial | Red | 0.25 in x 0.032 in | Appliances and equipment |
| Red Nylon Partially Insulated Piggyback Disconnect | Nylon, partial | Red | 0.25 in x 0.032 in | Socket/tab wiring systems |
| Red Nylon Partially Insulated Piggyback Disconnect | Nylon, partial | Red | 0.25 in x 0.032 in | Control cabinets, machinery |
| Yellow Nylon Partially Insulated Piggyback Disconnect | Nylon, partial | Yellow | 0.25 in x 0.032 in | Daisy-chaining, larger gauges |
Step up from vinyl to nylon when heat, vibration, or repeated mating cycles are present. Step up to yellow nylon when your conductor gauge is larger and you need stacked connections on a single tab.

FAQ
What is Disc Assembly, Part No. D41-8-05P, NSN 15760 used for?
It is used for quick connect/disconnect of electrical wires in control panels, appliances, and industrial machinery. The piggyback socket/tab design allows multiple connections to be stacked on a single 0.25 in x 0.032 in tab, enabling daisy-chaining without a separate junction block.
How do I choose between nylon and vinyl insulation?
Choose nylon for higher temperature and abrasion resistance in control cabinets and machinery. Choose vinyl for general-purpose panel wiring and appliances where cost is the priority. Both are partially insulated with a 0.25 in x 0.032 in tab.
Where can I buy Disc Assembly, Part No. D41-8-05P, NSN 15760 in Worldwide?
