How to choose the right Hydraulic Hose Fittings
PEHEL MACHINERY has been engaged in Hydraulic Components research and development for more than 20 years.
In Pehel, you can order hydraulic hose fittings in international standards.
The threads’ types in Pehel can be mainly divided into three groups- British Standards, American Standards and Metric Standards.
British Standards: BSP O-Ring Seal, BSPT, BSP Multiseal, BSP Flat Seal, BSP 60 Degree Cone Seal.
American Standards: SAE O-Ring Seal, NPT, JIC 74⁰ Cone Seal =JIC 37⁰ Flares, SAE 90⁰ Cone Seal, ORFS Flat Seal, NPSM 60⁰ Cone Seal, SAE Flange L.T. SAE Flange H.T.
Metric Standards: Metric Flat Seal, 60⁰ Cone Seal, Multi Seal, 74⁰ Cone Seal, 90⁰ Cone Seal, 24⁰ Cone O-Ring Seal L.T., 24⁰ Cone O-Ring Seal H.T. Standpipe Straight
Factors to consider when choosing the right fitting…
1. Pressure Rating: due to the risk of leakage, JIC fittings and NPT threads are not recommended for high pressure or high vibration applications. Most OEMs use o-ring face seals and DIN metric fittings for higher pressure applications.
2. Availability: because JIC and NPT fittings have been in the field for years, they are more easily accessible, less costly and a viable solution for low pressure applications.
3. Reliability: NPT fittings have been favored in the field in the past because leaks can be fixed by simply tightening the fitting. This has led to cracked fittings which can cause much more damage if left uncorrected. JIC is also still susceptible to cracked flares from overaggressive torqueing. This leads to the best reliability coming from o-ring face seal fittings and DIN metric fittings because of the elastomeric seal in the mating surface which eliminates over-torqueing and leakage risks.
4. Versatility: JIC fittings can connect to any foreign or American port and expand/reduce between sizes. JIC fittings are also typically stocked by vendors for easy accessibility.
