Check matching listingIdentify Dutton-Lainson DuraPatchUV by Size & MPN
Trying to match an existing DuraPatchUV packet or replace a partial sheet? Dutton-Lainson identifies the product by both a five-digit manufacturer number and a DP model code. The family contains four different sheet sizes, all activated by UV light, so the right selection begins with the original package and the dimensions of the repair.
Identify DuraPatchUV by manufacturer number
| MPN | Model | Nominal dimensions | Uncut area |
|---|---|---|---|
| 56711 | DP23 | 2 × 3 in | 6 sq in |
| 56712 | DP36 | 3 × 6 in | 18 sq in |
| 56713 | DP69 | 6 × 9 in | 54 sq in |
| 56714 | DP912 | 9 × 12 in | 108 sq in |
The smallest version, 56711 / DP23, measures 2 × 3 inches. The following numbers increase in size: 56712 / DP36 at 3 × 6 inches, 56713 / DP69 at 6 × 9 inches, and 56714 / DP912 at 9 × 12 inches. All dimensions refer to the uncut patch, not the final coverage after trimming.
Material and repair suitability matter. Dutton-Lainson says DuraPatchUV bonds to various substrates including polyethylene, fiberglass, metal, glass and wood, but specifically excludes polypropylene. Identify the actual surface material before ordering. The product description alone does not establish suitability for structural repairs, a pressurized system or potable-water-contact use.
What to check before replacing or using the patch
- Confirm the number on the foil pouch. The DP code and five-digit MPN are more reliable than guessing from the approximate packet size.
- Measure the original sheet. Compare its full width and length with the four sizes; a partially cut sheet cannot be reliably identified from what remains.
- Identify the substrate. The manufacturer lists polyethylene among its supported bonding surfaces but excludes polypropylene. Determine the actual tank, panel or housing material rather than assuming all plastics are equivalent.
- Check the storage condition. UV exposure cures the material. Keep unused patches protected in the original foil packaging and do not use a sheet that has hardened prematurely.
- Read the application sequence. Clean and dry the surface, apply the resin side firmly, then remove the outer film and expose the repair to UV or sunlight according to the instructions.
- Check the use case. A patch is not automatically approved for a drinking-water tank, pressurized line, structural component or an RV roof membrane. Review the repaired component's requirements first.
Distinguish it from ordinary repair tape
DuraPatchUV is a reinforced sheet that cures hard in UV light. It is not the same kind of product as a flexible, pressure-sensitive roof-sealing tape. Choose repair materials by substrate and service requirements rather than treating adhesive products as interchangeable.
