Frequently asked questions

Find answers to common questions about our products and services
  • This hose has a 3/4" female fitting on one end and a 3/8" male fitting on the other. The 3/4" female end typically connects to the outlet of an oil pump or dispensing unit, while the 3/8" male end connects to a delivery gun or nozzle — so make sure your equipment's ports match these sizes before purchasing.

  • The 2500 PSI rating indicates this hose is built to handle high-pressure oil delivery, making it appropriate for use with pressurized pump-driven dispensing systems rather than gravity-feed setups only. Always verify that your pump's output pressure stays within this limit to avoid hose failure.

  • The 3/8" inner diameter (I.D.) is a standard size for oil delivery hoses used in shop and lubrication equipment. It provides a balance between adequate flow volume and manageable hose stiffness, and it must be matched against the flow requirements of your dispensing system for optimal performance.

  • At 10 feet, this hose offers enough reach for most common shop scenarios — such as dispensing from a wall-mounted pump or portable oil caddy to a vehicle — but if your work area requires more distance between the pump and the vehicle, a longer hose would be needed.
