When assembling a suspension system, choosing the right fittings is just as important as choosing the right hoses. In this article, we'll explore the different types of fittings available, each with its own advantages and disadvantages.
1. Push In Fittings
Push-in fittings are popular for their ease of use. Simply push the hose into the fitting, making installation quick and hassle-free. However, be careful to cut the hose straight to avoid any risk of leakage; it is recommended to use a pipe cutter . To remove the hose, simply press the " button " on the fitting and gently pull the line. 
Benefits :
- Quick installation
- Ease of use
Disadvantages:
- Less reliable than other systems
- Susceptible to leaks if cut incorrectly
2. Screw Fittings
Screw-in fittings are often considered more reliable than push-in fittings. These fittings, usually included in Airmext kits, require a clamp that you slide onto the hose. Once the hose is on, simply tighten the clamp to create a seal , similar to that of Hard-Line fittings. Be careful not to over-tighten the clamp to avoid cracking the end of the hose.
Benefits :
- More reliable system
- Less risk of leakage
Disadvantages:
- Longer installation
- Risk of cracking if too much force is applied
3. Female or Male Fittings
Female and male fittings are essential for connecting your system to the tank or other components. Available in different shapes ( straight, 90°, T, Y ), these fittings allow you to adapt your installation optimally. To ensure a leak-proof seal, consider using Anti-Leak Sealant Liquid. 
Benefits :
- Flexibility in assembly
- Adaptability to various assemblies
Disadvantages:
- Requires additional accessories (Loctite)
4. Hardline Olive Fittings
For Hardline olive fittings, after cutting your pipe (copper or stainless steel), you must insert a screw-on sleeve and an olive. It is crucial to tighten them properly to avoid leaks. This system is known for its robustness and efficiency.
Benefits :
- Very reliable
- Excellent waterproofness
Disadvantages:
- More complex installation
- Requires special attention to tightening
5. NPT and G fittings
-
NPT : These tapered fittings provide a tight seal due to their tapered shape. Loctite is recommended to avoid any surprises.
-
G : These flat fittings are equipped with O-rings for sealing. Again, Loctite is recommended to ensure a good seal.
6. Fitting Size (Thread Diameter)
| Size (inches) |

Conclusion
Choosing the right type of fitting is essential to ensure the proper functioning of your system. Whether you opt for push-in fittings for simplicity, screw-in fittings for reliability, or olive fittings for Hardline systems, be sure to follow good installation practices to avoid leaks. Don't forget to use Loctite to ensure optimal sealing in your assemblies.
