Helix / SprayTech part 00078 is a leather V-packing designed to create a durable, leak-proof seal in the pump fluid section on compatible sprayers. This traditional sealing element uses leather construction to provide excellent wear resistance and conformability against the piston or rod. Replacing worn, hardened, or damaged leather V-packings restores pump efficiency and prevents fluid bypass.

The 00078 Leather V-Packing is a traditional sealing element used in the fluid section of compatible Helix and SprayTech sprayers. Constructed from specially treated leather, these V-shaped packings provide excellent sealing properties while maintaining flexibility and conformability against the moving piston or rod.
Leather V-packings have been used in fluid handling applications for decades due to their unique properties. The leather material absorbs a small amount of fluid, which actually enhances the seal by creating a slight swelling that improves contact with mating surfaces. Leather also offers excellent wear resistance and can tolerate some particulate matter that would damage synthetic seals.
Over time, leather packings can become hardened from heat or chemical exposure, worn at the sealing edges, or dried out from inactivity. A worn V-packing allows fluid to bypass the piston, resulting in pressure loss, reduced output, and material leakage. Replacing the leather V-packing restores the positive seal needed for efficient pump operation and consistent spray performance.
| Piston sealing | Creates a dynamic seal around the moving piston or rod |
|---|---|
| Pressure containment | Prevents fluid bypass during the pressure stroke |
| Self-lubricating | Leather absorbs fluid, providing natural lubrication |
| Pressure loss | Sprayer cannot maintain operating pressure |
|---|---|
| Fluid bypass | Material leaking past the packing into other areas |
| Hardened leather | Packing has become stiff and no longer conforms |
| Worn edges | Sealing surfaces are rounded or damaged |
Part 00078 is compatible with the following sprayer models. Always verify fitment using your equipment's parts diagram before ordering.
| Model | Component |
|---|---|

When replacing leather V-packings, these associated components are often inspected or replaced at the same time.
Inspect for scoring or wear that could damage new packings.
Check threads and sealing surfaces for damage.
Components that compress the V-packing set; inspect for wear.
