DWARFOO Oil Catch Can Universal 300ml Baffled Kit with Breather Filter — Anodized Aluminium, Adapter Set

The DWARFOO Oil Catch Can is a universal 300ml baffled oil-and-vapor separator kit that reduces intake contamination and helps keep engines cleaner.

This compact, welded aluminum catch can kit is built to trap oil, sludge and blow-by vapors before they re-enter the intake or valve train. Supplied with a ventilation breather filter, hose, adapters and mounting hardware, the kit is designed for straightforward installation on many cars and motorcycles. Anodized finish and included O-rings improve durability and sealing, while the internal baffling helps separate liquid from air for effective collection.

How will this catch can improve engine cleanliness?

By intercepting oil mist and carbon particles that would otherwise travel back into the intake system, the DWARFOO can reduce buildup on the throttle body, intake valves and manifold surfaces. Less contamination helps components operate closer to original condition between service intervals.

• 300ml baffled reservoir captures oil and condensate before it reaches intake parts
• Internal baffle design promotes liquid separation from crankcase vapors
• Anodized aluminum resists corrosion and keeps the unit structurally sound
• Comes with multiple adapter sizes (6mm, 8mm, 10mm) for varied hose connections

Is the DWARFOO catch can a universal fit and how do I install it?

The kit is intended as a universal solution: the 300ml can has M16×1.5 threads and includes adapter fittings and O-rings to accommodate common PCV and ventilation hose sizes. Installation typically requires selecting a mounting point with adequate clearance, connecting the inlet/outlet hoses, securing the can with the provided fixtures, and fitting the breather filter where appropriate.

• Compact dimensions: 68.2mm diameter, 112.5mm height for flexible positioning
• Adapter accessories included for 6mm, 8mm and 10mm hose interfaces
• All-welded tank plus O-ring sealing minimizes the chance of leaks
• Basic hand tools and a secure mounting location are all that’s generally required

What maintenance does the catch can need and when should I empty it?

Regular inspection and cleaning keep the system effective: check the reservoir weekly at first, then set a routine based on how quickly it fills. In cold conditions, condensed water can accumulate and freeze, so more frequent checks are recommended to avoid icing risks.

• Inspect reservoir weekly initially, then adjust interval by usage and engine condition
• Drain or wipe out collected oil and sludge during routine maintenance
• In sub-freezing temperatures check more often to prevent water accumulation and freezing
• Replace or clean breather filter as needed to maintain airflow and filtration

Will this catch can leak or fail under normal use?

The DWARFOO can is constructed from anodized aluminum with full-welded seams and O-ring sealing to limit leaks. When installed correctly and maintained, the design reduces risk of leakage and withstands typical engine bay conditions.

• Durable aluminum body with anodized coating to resist corrosion
• Welded construction plus O-shaped gasket for reliable sealing
• Tough supplied hose resists aging and cracking under heat and vibration

Who is this for? The DWARFOO Oil Catch Can Kit suits DIY mechanics, performance-minded drivers and motorcycle owners who want to reduce intake and valve contamination without complex modifications. It’s aimed at vehicles with limited space where a compact, universal 300ml can and included adapters make a practical upgrade to routine engine care.
