Stainless Steel Single Restricted Banjo Bolts – Precision Oil Flow Control for Turbochargers
Managing oil flow is critical for turbocharger performance and longevity. Our precision-engineered stainless steel restricted banjo bolts help regulate oil pressure, preventing excessive flow that can lead to turbo seal leaks and smoke issues. Manufactured in the United Kingdom from high-grade stainless steel, these banjo bolts offer superior durability, corrosion resistance, and a precision fit for high-performance applications.
Why Choose Our Stainless Steel Restricted Banjo Bolts?
-
Optimised Oil Flow
Each banjo bolt features a 1.5mm internal restriction to regulate oil pressure, reducing the risk of turbo seal leaks and excessive smoke.
-
Durable & Corrosion-Resistant
Machined from high-quality stainless steel, these bolts offer exceptional corrosion resistance, making them ideal for long-term use in turbo oil feeds.
-
Essential for Turbo Upgrades
Especially useful when switching from a journal-bearing turbo to a ball-bearing turbo, which requires lower oil flow.
-
Precision Fit for High-Performance Applications
CNC-machined threads ensure a secure, leak-free connection for turbo oil feeds in motorsport, automotive, and industrial applications.
-
Available in Multiple Sizes
Choose the correct thread size for your setup:
- M10 x 1.5 (1.5mm restriction)
- M12 x 1.5 (1.5mm restriction)
- 7/16"-24 UNF (1.5mm restriction)
What is a Restricted Banjo Bolt?
A restricted banjo bolt is designed to limit oil flow to sensitive components like turbochargers, preventing excess pressure that can force oil past seals and into the exhaust. This is particularly beneficial for ball-bearing turbos, which require lower oil volume compared to journal-bearing turbos.
Installation
To ensure a proper seal, you will need two copper crush washers per banjo bolt (not included). These washers help create a tight, leak-free connection between the banjo bolt, banjo fitting, and component.
Engineered for Performance, Trusted by Experts
From high-performance turbocharged engines to motorsport applications, our stainless steel restricted banjo bolts provide the precise oil flow control needed for reliability and efficiency. Upgrade today for optimised turbo performance and long-lasting durability.

What is a stainless steel single restricted banjo bolt?
A stainless steel single restricted banjo bolt is a specialised fastener designed to connect a banjo fitting to a component while regulating fluid flow. The built-in restriction helps control oil pressure, making it ideal for applications like turbocharger oil feeds where precise oil flow is crucial.
-
Why would I need a restricted banjo bolt for my turbocharger?
Turbochargers, especially ball-bearing types, require controlled oil flow to prevent seal leaks and excessive smoke. A restricted banjo bolt limits the oil flow to the turbo, ensuring optimal lubrication without over-pressurising the seals.
-
What sizes are available for these restricted banjo bolts?
We offer the following thread sizes, each with a 1.5mm internal restriction:
- M10 x 1.5
- M12 x 1.5
- 7/16"-24 UNF
This range ensures compatibility with various turbo oil feed setups.
-
Are these banjo bolts compatible with your custom braided hoses?
Yes, our stainless steel single restricted banjo bolts are fully compatible with our range of custom braided hoses, including those used for turbo oil feeds. They ensure a secure, leak-free connection in high-performance applications.
-
Do I need additional components for installation?
For a proper seal, we recommend using two copper crush washers (not included) with each banjo bolt—one on each side of the banjo fitting. These washers help create a tight, leak-free connection between the banjo bolt, banjo fitting, and component.
