Performance Fittings Aluminum Inline Y Block 3/8" NPT, Black - 38YBLK

The Performance Fittings Aluminum Inline Y Block 3/8" NPT (38YBLK) is the perfect solution for splitting fluid lines in your performance vehicle. Crafted from high-quality aluminum and finished in sleek black anodizing, this Y block offers corrosion resistance and durability. It features 3/8" NPT female inlet and outlets, making it compatible with a wide range of fuel, oil, or coolant plumbing setups. Its compact design ensures an easy fit even in tight spaces, making it ideal for race cars, hot rods, or any custom build that demands reliable and efficient fluid distribution.

Built with a single 3/8" NPT female inlet feeding two 3/8" NPT female outlets, this Y block lets you branch one fuel, oil, or coolant line into two runs without adding bulky adapters or extra hose clamps to the plumbing layout. The black anodized finish resists fading and corrosion under engine-bay heat and road grime, while the compact Y-block shape keeps the fitting low-profile so it tucks neatly against a firewall, chassis rail, or fuel cell bulkhead. Whether running a dual-carb fuel supply, splitting oil pressure to two gauges, or feeding twin coolant lines, this Y block delivers a precision-machined, leak-resistant connection point for the job.
