This is HEL Performance's range of oil system components, developed for both track and road use. HEL states its products have been raced competitively and tested extensively on the road.

The full CNC machining process for this oil system range is handled in-house, giving HEL close control over manufacturing and consistent build quality intended to last in demanding environments.

The twin bulkhead passthrough plate is built to fit into bespoke panels, custom brackets, firewalls and vehicle bulkheads, providing a secure way to pass fuel, oil, air or coolant between two sides of a partition. It has threaded inlet and outlet ports on both sides, compatible with a broad selection of adapters to suit different hose and fitting setups.

The bulkhead plate is lightweight and robust, and has an O-ring built into the rear face where it mounts, giving both weather resistance and a watertight seal at that point.

For AN16 (-16) or AN20 (-20) hose, a larger twin bulkhead passthrough plate is available.

The twin bulkhead passthrough plate is designed to mount to a variety of surfaces and is supplied with a drilling diagram to make installation straightforward. Technical drawings in the downloadable user manual can help confirm it suits a given application.

Compatible Hose and Adapters

Technical Specifications

A range of compatible hose, fittings and adapters is available for use with the bulkhead passthrough plates.

Package Contents

• 1 x HEL Twin Bulkhead Passthrough Plate

• 1 x Nitrile O-Ring

• 1 x Drilling/Mounting Diagram

Note

Before the vehicle is driven, the installer must check that every component is fully tightened and secure. Not doing so could cause oil loss or, in a worst case, engine failure.

HEL Performance's adapters and fittings route fuel, oil and water lines across a wide range of motorsport and automotive uses, in systems that must withstand high pressure, demanding conditions and extreme heat. Components - spanning stainless steel bleed nipples through to aluminium hose ends - are CNC-machined from premium materials, giving strong resistance to corrosion and wear.

HEL keeps production of its main stainless fittings, and many accessories, in-house using its own Star CNC equipment. Bleed nipples, banjo bolts and similar parts are all cut from solid stainless bar to precise tolerances, so quality stays consistent from batch to batch.

Bulkhead adapter fittings sized AN06 (-6) and AN16 (-16) are designed to pass fluid - typically coolant or fuel - through a vehicle bulkhead or custom panel.

This adapter does not include the bulkhead lock nut, which can be bought separately.
