PVC suction hoses are vital for fluid transfer in industries like agriculture, construction, and mining. The number of suitable fittings depends on length, pressure and application. But balance is key to avoid flow loss or leaks.
1. Short PVC Suction Hoses: 2–3 Fittings Max
Short hoses (e.g., for small pumps or portable use) need minimal fittings.
Start with a camlock fitting to connect the hose to the pump inlet. This ensures quick, secure attachment. Then add one elbow fitting if you need to route the hose around obstacles. Last, finish with a strainer fitting at the suction end to prevent debris from entering the hose. More than 3 fittings here restricts flow, as short hoses have less space to compensate for pressure drops.
2. Medium PVC Suction Hoses: 3–5 Fittings
Medium-length hoses (for irrigation or industrial transfer) handle slightly more fittings.
Include a camlock coupling at both ends for easy connection to pumps or tanks.
Add 1–2 tee fittings if you need to split the flow (e.g., for multiple irrigation lines).
Incorporate a check valve fitting to prevent backflow—critical for maintaining pressure.
Stick to 5 fittings max; extra joints increase leakage risk and reduce suction efficiency.
3. Long PVC Suction Hoses : 5–7 Fittings
Long hoses (for large-scale projects or remote transfer) require strategic fitting placement.
Use camlock adapters at both ends to match different pipe sizes or equipment.
Add 2–3 elbow fittings to navigate long distances without kinking the hose.
Include a pressure relief valve fitting to protect the hose from overpressure.
Add a union fitting for easy maintenance—this lets you disconnect sections without cutting the hose.
Avoid more than 7 fittings; each joint creates friction, lowering flow rate and straining the pump.
