Part 700-537 is a gasket used in the fluid section or sealing system of a wide range of RentSpray, ProMark, PowrTex, PowrLiner, Performer, Impact, Helix, Epic, and Airless Sprayer models. This gasket creates a fluid‑tight seal between components, preventing leaks and maintaining proper pressure. Replacing a worn, cracked, or compressed gasket restores reliable sealing and prevents fluid bypass.

Components: This is a single gasket; no additional parts are included.
The 700-537 gasket is a genuine OEM replacement sealing component used in the fluid sections, manifolds, or pump housings of many RentSpray, ProMark, PowrTex, PowrLiner, Performer, Impact, Helix, Epic, and Airless Sprayer units. It provides a critical seal between two mating surfaces, preventing fluid leaks, loss of pressure, and contamination.
Over time, gaskets can become hardened, cracked, or compressed due to heat, chemical exposure, and repeated pressure cycles. A failing gasket often leads to external leaks, pressure instability, or difficulty priming. Replacing a worn gasket with 700-537 restores a leak‑free seal and reliable machine operation.
| Seals mating surfaces | Prevents fluid leakage between pump housing, manifold, or fluid section components |
|---|---|
| Pressure retention | Helps maintain consistent operating pressure by eliminating bypass |
| Contamination prevention | Blocks entry of dirt or moisture that could damage internal components |
| Visible leaks | Fluid seepage around the gasket area |
|---|---|
| Hardening or cracking | Gasket material becomes brittle, cracked, or disintegrates upon removal |
| Compression set | Gasket no longer springs back; has taken a permanent flat shape |
| During service | Always replace gaskets whenever the sealed joint is disassembled |

When replacing a gasket, it is often wise to inspect and replace other sealing components or fasteners to ensure a leak‑free repair.
Adjacent O‑rings or dynamic seals may be worn and should be replaced at the same time.
Inspect mating surfaces for nicks, corrosion, or warping that could prevent a good seal.
Check bolts or screws for thread damage; use correct torque when reassembling.
