Quick Connects & Fittings
KobraJet hoses are typically available with pre-installed quick connects (stainless or brass), but they can also be purchased bare if you’re custom-building a setup.
Most common end configurations:
- 3/8" male NPT
- 3/8" female swivel NPT
- M22 fittings (less common on commercial units)
Pair your hose with stainless quick disconnects to maximize corrosion resistance and system longevity.
Tips for Choosing the Right KobraJet Hose
- Check your machine’s PSI and GPM ratings. Match hose reinforcement and diameter accordingly.
- Prioritize flexibility if you’re mobile or work in tight spaces. The blue or gray single-wire is ideal.
- Use a hose reel to store longer lengths and reduce wear from dragging.
- For long runs (75–100 ft+), go with 3/8" for better flow.
Care and Maintenance Tips
- Don’t leave pressurized. Always relieve pressure after use to prevent premature wear.
- Avoid sharp kinks or tight coils—use a hose reel or wide loops.
- Store indoors when possible to prevent UV or ozone degradation.
- Flush regularly if used with chemicals or hot water.
- Inspect ends frequently for leaks or swelling at the crimps.
