Au-ve-co Products 10110 Plastic Vacuum Tee Fitting

Product Description

The AU-VE-CO PRODUCTS 10110 is a plastic vacuum tee fitting designed for use in automotive and light-duty HVAC vacuum line systems. This three-way tee connector allows a single vacuum source to be split or branched across two circuits, maintaining signal integrity in low-pressure vacuum control systems. Constructed from plastic, it is lightweight and resistant to the mild vacuum pressures typical of automotive climate control and accessory circuits. All three ports measure 0.25 inches, making it a uniform-bore fitting with no reduction in line diameter. Licensed technicians and experienced DIYers performing vacuum line repair or system diagnostics will find this fitting straightforward to install.

This fitting is used in automotive vacuum distribution systems, including those controlling HVAC blend door actuators, vacuum-operated accessories, and emissions-related components. It is suited for low-pressure vacuum circuits where a plastic fitting provides adequate durability. Typical applications include splicing into an existing vacuum harness, replacing a cracked or broken tee junction, or extending a circuit during system modification or repair.

Key Features

• Uniform 0.25 inch bore on all three ports for consistent vacuum flow
• Plastic construction keeps weight minimal at 0.01 pounds
• Three-way tee configuration allows vacuum line branching or splitting
• Compact form factor fits in tight engine bay and under-dash routing

Compatibility

Designed as a replacement or repair fitting for automotive vacuum systems using 0.25 inch vacuum line tubing. No specific vehicle or system compatibility data was provided by the manufacturer for this part.

Installation Notes

Installation is typically performed by automotive technicians or HVAC service pros working on vehicle climate control or vacuum accessory circuits. Disable the engine and relieve any residual vacuum pressure before disconnecting existing lines. Ensure vacuum hose inner diameter matches the 0.25 inch port size for a secure, leak-free connection. Inspect surrounding hose sections for cracking or hardening and replace as needed before returning the system to service.
