Description
Industrial Layflat Discharge Hose, Nitrile/PVC, 1-1/2" ID, Through the Weave, Black, 300 PSI, 50 Ft
The 1-1/2 inch industrial layflat discharge hose is a flat-rolling nitrile/PVC rubber hose that moves water away from construction sites, plants, and spill zones. Its through the weave construction bonds the rubber into woven polyester as one solid wall at 300 PSI. Construction contractors, municipal crews, and remediation teams use this chemical resistant discharge hose where runoff contains fuel, oil, or hydraulic fluid.

Key Features
- Through the weave discharge hose construction bonds the nitrile/PVC rubber directly into woven polyester as one solid wall with no separate liner to delaminate
- The nitrile PVC discharge hose compound resists petroleum, fuel, oil, hydraulic fluids, and vegetable oils that destroy standard PVC hose
- This industrial layflat discharge hose handles 300 PSI working pressure, double the rating of standard PVC discharge hose
- This layflat discharge hose with NPSH fittings threads onto pump outlets, hydrant adapters, and nozzles with a spanner wrench for a secure seal
- Chemical resistant discharge hose compound operates from -37°C to 81°C for year-round deployment in extreme temperatures
- Hard-coat aluminum fittings, male x female swivel, crimped onto the hose for a lightweight, corrosion-resistant permanent connection
- 1-1/2 inch inside diameter fits most portable centrifugal pump outlets without reducers or adapters
- Layflat design stores flat on trucks and job site racks, expands to full round cross-section under pressure
- UL Listed and NFPA Compliant for municipal and industrial procurement specifications
Applications
- Construction contractors connect this industrial layflat discharge hose to dewatering pumps for trench, pit, and foundation excavation drainage.
- Industrial plant operators run this nitrile PVC discharge hose for washdown and process water discharge in facilities handling oil, fuel, and hydraulic fluid.
- Environmental remediation crews deploy this 1-1/2 inch layflat discharge hose to pump contaminated groundwater from spill sites and tank removals.
- Municipal utility crews use this chemical resistant discharge hose for hydrant flushing and water main testing where runoff contains sediment and trace petroleum.
- Rental fleet managers stock this pump discharge hose assembly for equipment rental packages that include portable pumps and discharge lines.
How Through-the-Weave Construction Works
Standard discharge hose layers a rubber tube inside a woven jacket and bonds them with adhesive. The liner separates over time at fold points, kinks, and high-pressure cycles. In a through the weave discharge hose, the manufacturing process is fundamentally different.
The nitrile PVC discharge hose compound is extruded through the openings in the circularly woven polyester during manufacturing. The rubber fills every gap in the weave and cures as one continuous wall. No separate liner exists to pull away, and no adhesive is needed. The rubber and the reinforcement become one piece.

Frequently Asked Questions
What Is Through the Weave Hose Construction?
In through the weave construction, the rubber and woven reinforcement are manufactured as one solid piece instead of two separate layers bonded together. The hose wall cannot delaminate at fold points or kink zones. This construction handles repeated rolling, dragging, and high-pressure cycling without liner separation.
How Does a Nitrile PVC Discharge Hose Compare to Standard PVC?
When comparing nitrile vs PVC discharge hose, the nitrile/PVC blend resists petroleum, fuel, oil, and hydraulic fluids that degrade plain PVC. It also handles higher pressure (300 PSI vs 90 to 150 PSI for PVC) and a wider temperature range. PVC costs less but fails faster in chemical environments.
What Size Discharge Hose Do You Need for a Dewatering Pump?
To determine what size discharge hose for a dewatering pump, match the hose diameter to the pump outlet. Most portable centrifugal pumps use a 1-1/2 inch or 2 inch outlet. A 1-1/2 inch layflat discharge hose fits standard connections for trench, pit, and foundation dewatering.
Should You Choose NPSH or Camlock Fittings for Discharge Hose?
When choosing NPSH vs camlock fittings for discharge hose, consider how often you disconnect. NPSH threads onto pumps, hydrants, and nozzles with a spanner wrench for a secure, leak-free seal. Camlocks connect and disconnect by hand in seconds for rental and quick-swap applications.
Can You Use Nitrile Discharge Hose for Oil and Fuel?
Yes. The nitrile/PVC compound resists petroleum, diesel fuel, gasoline, hydraulic fluid, and vegetable oils at concentrations found in construction runoff, industrial washdown, and remediation pumping. It is not rated for concentrated acids, ketones, or chlorinated solvents.
