Identify Camco Freshwater Prefilters and Screened Washers
Camco's water-hose connection accessories do different jobs. Some help trap sediment, some filter water in a hose connection, and others simply keep the fitting watertight. Compare the exact MPN and component type to avoid choosing a plain washer when a screen or prefilter is needed.
Filter and washer functions
| Camco MPN | Item | Published rating | Package |
|---|---|---|---|
| 40048 | Sediment prefilter | 20-micron | Single |
| 40646 | Inline water filter | 150-micron | Single |
| 20183 | Screened hose washers | 60 × 50 mesh | 3-pack |
| 20153 | Self-locking hose washers | No filter screen | 10-pack |
A micron rating refers to a particular filtration function, not a guarantee that untreated water is safe to drink. Choose a suitable system for the water source.
Choosing the right freshwater accessory
- Identify whether you need a separate sediment prefilter, an inline hose filter, a screened sealing washer or a plain sealing washer.
- Camco 40048 is a sediment prefilter for use ahead of suitable inline filters; 40646 is a separate inline hose filter with a listed 150-micron rating.
- 20183 supplies three screened washers with stainless 60 × 50 mesh. It helps stop grit at a compatible garden-hose connection but does not replace a full filtration system.
- 20153 supplies ten self-locking rubber washers without screens. These help seal the coupling, not filter drinking water.
- Inspect washers and filter fittings for damage, contamination or missing seals. For potable water, avoid reusing a filter with an unknown service or storage history.
