FlowGuard Gold® CPVC vs. Generic CPVC

Product Comparison

Homeowners and contractors demand reliable, high-quality piping systems that deliver safe, clean drinking water over the long term. FlowGuard Gold® CPVC pipe and fittings have a reputation for quality and 60 years of proven performance to exceed homeowner and contractor expectations. 

Not all CPVC compounds, however, are the same and only a complete FlowGuard Gold piping system will provide the consistency and durability you’ve come to expect from FlowGuard Gold CPVC. While it is true that generic CPVC materials can save a few pennies in the short-term, the long term liability cost can wash out any immediate savings.

 

FlowGuard Gold CPVC Piping and Fittings Outperform Generics in Testing

Since 1959, FlowGuard Gold CPVC has been held to the highest standards of excellence. To confirm our superior performance, Lubrizol conducted physical testing on both FlowGuard Gold fittings and generic fittings produced on the same equipment by the same manufacturer. 

FlowGuard Gold CPVC fittings outperformed generic fittings in all sizes and geometries tested.

 

Quickburst Test Results Prove Superiority of FlowGuard Gold Fittings

  FlowGuard Gold Fittings Generic Fittings
Overall Fitting Performance 100% 88%
½” Fittings 100% 90%
¾” Fittings 100% 84%
Elbows 100% 89%
Couplings 100% 81%
Tees 100% 96%

Fitting performance is an important part of the story, but system performance relies equally on using high quality pipe and fittings. To help evaluate the performance of FlowGuard Gold pipes compared to our competitors, we sampled all of our licensed manufacturers’ and competitors’ pipes and put them to the test.

In both impact strength and sustained pressure resistance, all of the generic pipes tested performed significantly lower than the FlowGuard Gold pipes tested. When subjected to excessive temperature testing, FlowGuard Gold pipes were the only samples that did not immediately fail.

Superior Performance By Design

Generic CPVC manufacturers either source their resins and compounds overseas (more than 85% of non-Lubrizol CPVC resins come from in Asia) or source their resins from one company and compound them in a separate facility before sending the finished product to the pipe manufacturer. 

While generic CPVC pipe and fittings manufacturers may mix and mingle their resin and compound sources, resulting in inconsistent products from one batch to another, the compounds used to make FlowGuard Gold CPVC materials are made from Lubrizol’s own resins with both the resin manufacture and the compounding process occuring in the same plant, under Lubrizol’s control, in Louisville, KY.

Tens of billions of feet of FlowGuard Gold CPVC piping systems installed globally during the past 60 years attest to FlowGuard Gold CPVC piping quality, consistency and reliable long-term performance. 

 

Warranty Implications of a Complete System

Lubrizol’s manufacturing partners each offer a warranty on their own pipe and fitting products, but contractors and builders can also work with Lubrizol to qualify for Lubrizol’s Preferred Contractor Program, which would allow qualified contractors and builders to offer an additional warranty on the plumbing system, backed by Lubrizol, to their customers.

Introducing non-FlowGuard Gold CPVC components to a plumbing system places your warranty protection at risk. Lubrizol’s warranty does not cover failures of generic CPVC systems or components within a system.

When contractors mix generic fittings or pipe with FlowGuard Gold CPVC during installation, they not only introduce underperforming components to the system, but they may undercut their warranty protection on the system.

 

How to Verify Piping and Fittings are FlowGuard Gold CPVC

While generic CPVC clearly comes with lower performance, it also comes with a lower price. Most business owners are savvy enough to understand the risks associated with this tradeoff and insist on a complete FlowGuard Gold system.

Unfortunately, in the field, it is possible for generic CPVC products to pop up at distribution and make their way onto your jobsites. To ensure the quality of product on your jobs it is important to verify your products prior to installation.

FlowGuard Gold pipe can be easily identified by inspecting the print line for the trademark gold stripe and “FlowGuard Gold®” mark. You can identify the specific Lubrizol manufacturing partners as well through their brand name on the pipe.

Fittings can be a bigger challenge to clearly identify and, as a result, there is a much higher risk of contractors unintentionally mixing in generic fittings and diminishing the quality of their installations.

Contractors who purchase fittings in bulk can verify those fittings by looking for the FlowGuard Gold logo on the packaging. If the packaging does not have the FlowGuard Gold logo – the fittings are not FlowGuard Gold CPVC.

If you’re buying fittings outside of their original packaging – or inspecting your inventory to weed out non-FlowGuard Gold fittings – you can also look for markings on the fitting itself.

FlowGuard Gold fittings will be marked with the names of our manufacturing partners:

  • Charlotte fittings will be marked with “Charlotte” or “CPF”
  • NIBCO fittings will be marked “NIBCO”
  • Genova fittings will be marked “Genova”
  • Bow fittings will be marked “BOW”

Common generic CPVC fittings include Spears, KBI and Lasco brands, along with a variety of Asian brands, which occasionally pop up in distribution. These brands are not made from FlowGuard Gold CPVC and should not be installed as part of a FlowGuard Gold CPVC plumbing system.

If you run into a distributor offering unusually low pricing on CPVC fittings (in some cases as much as 50% lower than FlowGuard Gold fittings) don’t be fooled – tell your distributor you insist on FlowGuard Gold CPVC fittings. A few pennies saved on the invoice are not worth the risk you’ll be adding to your system.
