Largest Selection of High-Quality Pipe Fittings in the Industry

IPP’s selection of fittings includes sizes from ½” to 63” and difficult-to-find parts, such as the corrosion-resistant PPDI (Polypropylene Encapsulated) backup ring.

Quality Assurance Testing on All Products

IPP’s 45,000 square foot HDPE production facility houses a sophisticated in-house lab where analysts perform a variety of quality tests on all IPP products, including:

  •  Long-term hydrostatic testing,
  • Burst testing,
  • Melt index testing,
  • Carbon black content testing and
  • Ultrasonic testing.

While many companies do the absolute bare minimum to maintain compliance, IPP performs routine in-house testing to ensure all parts meet specifications and then sends out the results for certification periodically. Customers can request testing records from IPP’s files at any time.

For additional quality assurance, IPP’s production facility also follows careful procedures to ensure the traceability of all parts produced. This includes tracking when a product was
produced and by whom.

Fast Shipping with No Expedite Fees

IPP produces large diameter HDPE fittings 24 hours a day, 7 days a week, year-round (with the exception of preventative maintenance days). Therefore, IPP’s distribution facility is able to carry the largest selection of in-stock HDPE fittings in the industry and respond to most customer needs within 24 hours. This is unique in an industry where 4-6 week back-orders are common occurrences.

Even beyond the speed of delivery and order fulfillment, IPP is concerned with providing the best purchasing experience for its customers possible. Customers receive orderacknowledgements via email for each transaction and ship notifications when orders have been fulfilled.
