Harvel Clear™ Rigid PVC piping provides a versatile, cost-effective alternative for many piping applications, particularly those where visual monitoring of processes is critical. The benefits of rigid PVC piping are well recognized: exceptional corrosion resistance; smooth interior walls for unimpeded flow and reduced sediment buildup; non-contaminating for purity applications; fast, reliable solventwelded connections; good pressure-bearing capability; and ease of handling and installation, to name a few. All of these important benefits are now available in a unique product with optimum clarity. This clarity provides the all-round visibility that specialized applications demand whether it be clean room applications, sight glass, dual-containment or various other processing applications where continuous monitoring is necessary.


Harvel Clear™ PVC piping is produced from a rigid, virgin Polyvinyl Chloride (PVC) compound with a Cell Classification of 12454 per ASTM D1784. This material enables Harvel Clear™ piping to safely carry a maximum service temperature of 140F when appropriate temperature/pressure de-rating factors are applied. In addition to exhibiting desirable physical properties and optimum transparency, this material is listed by the National Sanitation Foundation as being safe for use with potable water (NSF International Standard 61), and also complies with the provisions of Title 21 of the United States FDA Code of Federal Regulations as being safe for use in food contact applications. Due to the non-contaminating nature of Harvel Clear™ PVC piping products, extensive chemical extraction testing has been conducted to evaluate their use in ultra-pure applications. Details pertaining to extractable analysis is available from Harvel upon request. Harvel Clear™ provides similar reliable chemical resistance properties that conventional PVC piping has demonstrated over the years. In general, it is resistant to most acids, bases, salts and oxidants. Detailed chemical resistance data is available and should be referenced for proper material selection. Since this material is a nonconductor, Harvel pipe is not subject to electrolytic or galvanic corrosion. This material is compatible with conventional PVC pipe, fittings and valves, and can be incorporated into existing PVC systems via the solvent cement joining process. In addition to a full line of Schedule 40 clear fittings for most applications, an endless array of standard PVC components and accessories are readily available. Harvel Clear™ PVC exhibits excellent flammability characteristics as well.

Typical Applications

Harvel Clear™ provides several advantages over traditional materials in many applications. It is routinely used as dual-containment piping for high purity piping runs where quick identification of primary tubing and visual leak detection is critical. From semiconductor clean rooms to aggressive chemical processing applications, Harvel Clear™ provides durable leak-free containment piping with optimum visibility. Compatibility with standard PVC piping systems makes the product ideal for sight gauge assemblies in many applications. The wide range of sizes and clear fittings available enable custom in-process monitoring of process fluids.

Other applications include:

  • Chemical Processing
  • Medical/Hospital Use
  • Electroplating
  • Food Processing
  • Dual Containment
  • Displays/Exhibits
  • Laboratory Applications
  • Environmental Applications
  • Cosmetics
  • Beverage Processing
  • Visual Test Equipment
  • Fish Hatcheries
  • Sight Glass

Product Ratings and Capability

Harvel Clear™ pipe and fittings are manufactured in IPS sizes to Schedule 40 & 80 dimensions for optimum performance. This provides sufficient wall thickness for most pressure applications without jeopardizing clarity. As a rigid PVC piping, Harvel Clear™ PVC maintains its integrity in harsh environments. It is suitable for use in both positive and negative pressure applications (i.e., vacuum service). As with all schedules of thermoplastic pipe, pressure rating is dependent on the pipe diameter selected as well as the operating temperature of the system. As temperatures rise, the pressure rating of the system decreases. Smaller diameter piping can withstand higher pressures than large diameter piping. Refer to the table below for dimensions, tolerances and pressure ratings.
