Uponor’s tubing is manufactured using the Engel method of cross-linking, which creates the most flexible and kink-resistant PEX available. This process allows the tubing to expand up to 300% for fitting installation and then return to its original dimensions, creating incredibly secure connections.
The 25-year transferable limited warranty provides peace of mind for homeowners, though recent lawsuit developments have raised questions about long-term reliability for systems installed between 2010-2021. Despite these concerns, Uponor remains the preferred choice for many professional plumbers who value its consistent quality and established track record.
Reasons to Buy
Industry-leading flexibility and kink resistance, proven track record in demanding applications, and comprehensive warranty protection when properly installed.
Reasons to Avoid
Significant price premium over alternatives, ongoing lawsuit concerns affecting certain installation periods, and supply chain issues that can cause project delays.
Understanding PEX-A Technology
PEX-A (cross-linked polyethylene type A) represents the most advanced form of PEX tubing available for residential plumbing applications. The key difference between PEX-A and other types lies in the manufacturing process and resulting molecular structure.
The Engel method used in PEX-A production creates the highest degree of cross-linking (approximately 85%), resulting in superior flexibility and shape memory. This allows the tubing to expand when heated and return to its original dimensions when cooled, which is essential for the expansion-fit connection system.
When comparing different types of plumbing pipes, PEX-A stands out for its ability to withstand freezing conditions without bursting. The material can expand significantly when water freezes inside, preventing the catastrophic pipe failures common with copper and CPVC systems.
Both Apollo and Uponor manufacture their PEX-A products to meet ASTM F876/F877 standards, ensuring consistent performance regardless of brand. This standardization means that expansion fittings, tools, and installation techniques work identically across both manufacturers.
Head-to-Head Comparison
Compatibility and Interchangeability
One of the most important factors in this comparison is that Apollo PEX-A is fully compatible with Uponor ProPEX fittings and tools. The dimensions, expansion ratios, and connection requirements are identical, allowing you to mix and match components from both manufacturers without issue.
This compatibility extends to expansion tools, sleeves, and all connection hardware. Professional plumbers frequently use Apollo tubing with Uponor fittings or vice versa, confirming that there are no practical differences in installation procedures or performance.
The only consideration is maintaining consistency within your expansion system. While you can mix brands, it’s best practice to use the same brand of expansion sleeves/rings with the corresponding fittings to ensure optimal performance and warranty compliance.
Installation Process and Tools
Both Apollo and Uponor require the same basic installation process using expansion-fit technology. This involves expanding the PEX-A tubing with a specialized tool, inserting the fitting, and allowing the tubing to contract back to create a secure connection.
The necessary tools include an expansion tool (manual or automatic), appropriate expansion sleeves/rings, and a pipe cutter. For those interested in plumbing installation projects, the initial investment in tools typically ranges from $150-300 for a quality expansion tool.
Cold weather installation presents challenges for both brands, as PEX-A becomes less flexible in low temperatures. Professionals recommend using a heat gun to warm the tubing before expansion when working in temperatures below 40°F, regardless of brand.
Performance and Reliability
Both Apollo and Uponor PEX-A products meet or exceed industry standards for pressure rating (typically 500 PSI at 73°F) and temperature range (up to 200°F for hot water applications). Real-world performance is virtually identical when properly installed.
Uponor holds a slight edge in professional preference due to its longer history and established reputation in the industry. Many plumbing contractors have been using Uponor for decades and are hesitant to switch, even when presented with significant cost savings from Apollo.
However, recent years have seen growing acceptance of Apollo among professionals, particularly those who value the cost savings and improved availability. Some plumbers have even noted that Apollo’s expansion rings feature better anti-slip properties than Uponor’s design.
The Lawsuit Factor
Perhaps the most significant differentiator in recent years is the legal landscape. Uponor faces multiple class action lawsuits related to their AquaPEX systems installed between 2010-2021, alleging premature failures due to manufacturing defects.
These lawsuits claim that certain Uponor PEX-A products manufactured during this period may experience failures within 3-10 years of installation, well below the expected lifespan. The litigation specifically mentions issues with the Engel method manufacturing process during these years.
Apollo, manufactured by Mosack Group, faces no similar lawsuits or widespread failure reports. This legal uncertainty surrounding Uponor has led many contractors and homeowners to reconsider their brand preference, especially for projects where long-term reliability is paramount.
