Au-ve-co Products 12918 Plastic Vacuum Tee Fitting

Product Description

The AU-VE-CO PRODUCTS 12918 is a plastic vacuum tee fitting designed for automotive vacuum line applications. This three-way tee connector measures 3/16 x 3/16 x 3/16 inches across all three ports, providing a uniform-bore split in a vacuum circuit. The plastic construction keeps weight minimal at 0.01 pounds, and the symmetrical port sizing simplifies installation by eliminating directional orientation concerns. HVAC technicians, automotive service technicians, and fleet maintenance professionals use this type of fitting to branch or splice vacuum lines in engine management, HVAC blend door actuation, and emission control systems.

This fitting is suited for low-pressure vacuum circuits found in automotive and light-truck applications. Typical uses include repairing or extending vacuum harnesses routed to actuators, check valves, EGR components, and climate control systems. The uniform 3/16-inch port size matches the most common vacuum line diameter used in domestic and import vehicle engine bays. It is also used in stationary small-engine and equipment applications where 3/16-inch vacuum tubing is present.

Key Features

• Uniform 3/16-inch ports on all three legs for straightforward inline branching
• Plastic construction provides lightweight, corrosion-free performance in low-pressure vacuum circuits
• Symmetrical tee geometry eliminates orientation errors during installation
• Compact form factor fits in tight engine-bay routing paths
• Compatible with standard 3/16-inch vacuum tubing used across a wide range of automotive applications

Compatibility

Designed as a replacement or repair fitting for automotive vacuum systems using 3/16-inch vacuum tubing across engine management, emission control, and HVAC actuator circuits.

Installation Notes

Installation should be performed by a qualified automotive or HVAC technician with the ignition off and the vehicle engine at rest. Push each vacuum line fully onto the tee barbs until seated to ensure an airtight connection. Inspect surrounding vacuum hoses for cracks or hardening before reinstalling the repaired circuit. Vacuum line work on vehicles with active emission controls may be subject to applicable state and federal inspection standards.
