Frequently Asked Questions
What Is NPSH Thread on a Discharge Hose?
NPSH stands for National Pipe Straight Hose thread. It is a straight thread that seals with a gasket, not tape or pipe dope. This NPSH discharges hose threads directly onto pump discharge ports, hydrant adapters, and fire department connections with matching NPSH threading. No wrenches or sealant needed.
What Is the Difference Between Nitrile and PVC Discharge Hose?
When comparing nitrile hose vs PVC discharge hose, the difference is chemical resistance. Nitrile uses a rubber compound bonded through woven textile that resists petroleum, fuel, and chemicals PVC cannot handle. A rubber layflat discharge hose holds higher working pressure at 300 PSI versus 75 to 150 for PVC.
What Is the Best Hose for Pump Discharge?
The best hose for pump discharge matches the pump outlet thread, working pressure, and media compatibility. For chemical or petroleum environments, a rubber layflat hose handles media that PVC cannot. Match the hose inside diameter to the pump port size. A 1-1/2 inch hose fits most portable centrifugal pump outlets.
What Chemicals Can Nitrile Discharge Hose Handle?
Nitrile/PVC rubber compound resists petroleum products, crude oil, refined fuels, hydraulic fluids, vegetable oils, and many low-concentration industrial chemicals. It does not handle concentrated acids, ketones, or chlorinated solvents. A rubber discharge hose with through-the-weave construction prevents chemicals from reaching the reinforcement textile.
Should You Choose Brass or Aluminum NPSH Fittings?
When choosing brass vs aluminum NPSH fittings, consider the media. Brass resists corrosion in chemical, saltwater, and petroleum environments. Aluminum is lighter but corrodes faster with chemical contact. A nitrile rubber layflat hose with brass fittings suits industrial discharge where the hose handles fuel, oil, or chemical media.
