Description

High-Strength Chemical Feed Delivery with 3/8 Inch OD White Polyethylene Tubing

The 3/8 inch OD white polyethylene tubing provides reliable fluid transfer for chemical dosing and water treatment systems. Made from hard polyethylene, it combines a rigid construction with chemical resistance. As a result, it is a practical choice for commercial and industrial fluid handling applications.

Durable Hard Polyethylene Construction

The 3/8 inch OD white polyethylene tubing features a Shore D 45 hardness rating. Its rigid, kink-resistant construction helps maintain consistent flow during operation. In addition, the tubing has a 1/4-inch inside diameter and a 0.06-inch wall thickness.

The natural white, semi-clear finish also provides some visibility of the fluid inside the tubing. This feature can help operators monitor flow during system operation.

Pressure and Vacuum Rated Tubing

This hard polyethylene tubing supports operating pressures up to 125 PSI at 75°F. It is also vacuum rated up to 28 in. Hg. Therefore, it can support compatible suction and fluid transfer applications within its specified operating limits.

The tubing operates within a temperature range of -50°F to 140°F. Its 10-foot roll length makes it convenient for new installations and routine tubing replacement.

Compatible with Common Fluid Handling Fittings

The 3/8 inch OD white polyethylene tubing works with compatible compression and push-to-connect fittings. This makes it easy to integrate into many water treatment and chemical feed systems.

It is suitable for chemical metering pumps, chemical dosing systems, water treatment equipment, HVAC systems, and industrial fluid handling. However, users should always confirm tubing compatibility with the specific chemical, pressure, temperature, pump, and fitting before installation.

Available from Water Treatment Supply, this 3/8 inch OD white polyethylene tubing provides a durable solution for compatible chemical and fluid transfer applications.

Technical Performance Parameters 

Review the physical measurements, chemical capabilities, and mechanical limits of this hard polyethylene fluid tubing: 

Mechanical Integrity & Fitting Adaptability

  • Structural Kink Resistance: Engineered with a 3-3/4″ minimum bend radius to prevent flow restriction around tight panel turns.
  • Vacuum System Compliance: Rated for up to 28 in Hg vacuum, eliminating line collapse on suction-lift feed pumps.
  • Fitting Seals: Uniform outer diameter tolerance ensures tight mechanical seals in compression nuts and push-in fitting O-rings.

Use Cases & Industry Applications:

  • Chemical Metering Pump Lines: Function as primary suction and discharge tubing for chlorine, acid, coagulant, and polymer dosing pumps.
  • Water Treatment & RO Systems: Ideal for carrying permeate, concentrate, or pre-treatment chemicals in commercial reverse osmosis units.
  • Cooling Tower & Boiler Feed Lines: Connects water treatment controllers to chemical injection quills on cooling tower loops.
  • Laboratory & Analytical Sampling: Provides an inert fluid transfer line for side-stream process sampling and online monitoring sensors.

FAQs

FAQs

  1. What chemical solutions can be safely pumped through this 3/8 inch OD white polyethylene tubing?
    This hard polyethylene tubing 3/8 OD is highly resistant to a broad spectrum of water treatment chemicals, including sodium hypochlorite (chlorine bleach), diluted acids, caustic solutions, alum, and liquid fertilisers. Its non-reactive polymer construction prevents chemical leaching and tube degradation during continuous feed operations.
  2. Is this tubing suitable for suction lift lines on chemical metering pumps?
    Yes. With a vacuum rating of 28 in Hg and a Shore D 45 hardness rating, this rigid line will not flatten or collapse under negative pressure. This makes it an ideal choice for metering pump suction draw tubes running directly from chemical storage drums or tanks.
  3. What type of fittings work best with this white chemical feed tubing?
    This tubing features precise outer diameter tolerances that make it fully compatible with standard plastic and brass compression fittings (with inner pipe support inserts) as well as push-to-connect (quick-connect) fitting assemblies.
  4. How does the temperature of the fluid affect the pressure rating of this tubing?
    The tubing is rated for a maximum operating pressure of 125 PSI at 75°F (24°C). As fluid temperatures approach the upper limit of 140°F (60°C), the maximum safe operating pressure decreases. For high-temperature or continuous high-pressure hot water lines, pressure derating should be calculated accordingly.
  5. What is the minimum bend radius for this 10 ft polyethylene tubing roll?
    The recommended minimum bend radius is 3-3/4 inches. Bending the tubing tighter than this radius may cause kinking or stress fracturing along the outer wall, which can impede chemical flow or compromise line pressure capacity.
