Pentair TR140 Air Relief Tube 150042

This air relief tube is ideal for pool owners operating the Pentair TR140 sand filter who notice air buildup, inconsistent pressure readings, or reduced flow after startup. Over time, internal tubes can become brittle from constant water exposure and chemical contact. Replacing the tube ensures proper air evacuation during system priming and backwash cycles. It’s a preventive maintenance step that supports consistent filtration and protects downstream equipment like heaters and salt systems.

Best for: Pentair TR140 sand filter maintenance

Not ideal for: Other Pentair Triton models or cartridge/DE filter systems

Aftermarket internal tubing may not match the precise dimensions or material durability required for the TR140’s internal design. The Pentair 150042 is engineered for exact fitment and reliable performance under pressure. Using OEM components helps prevent leaks, misalignment, or improper venting.

Pro Tip: If you’re replacing the air relief tube, inspect the air relief assembly and pressure gauge at the same time. Air management components often wear together, and addressing them simultaneously ensures consistent system operation.

In real-world pool service, trapped air inside a sand filter often goes unnoticed until performance drops. The Pentair TR140 Air Relief Tube (150042) restores proper venting and stabilizes internal pressure for reliable filtration. It’s a simple internal replacement that protects pump efficiency and water clarity.
