TC Bros. DIY Round 5″ Oil Tank

The size and shape of factory oil tanks often means they can't be reused without lots of fabrication, especially when used on a motorcycle that's been converted to a rigid rear. Why not spend your fab time making something custom?

• 10"L × 5" OD
• Oil capacity is nearly 3 quarts
• 100% TIG welded mild steel
• Available with flat or domed (pill-style) ends
• Pressure tested to ensure quality, leak free performance
• CNC-machined, knurled aluminum cap included (1-5/16"-12)
• 1/4" NPT CNC-machined bungs included for easy plumbing 
• Proudly made in the USA (and wherever you complete the work!)

This TC Bros. Round Oil Tank has dimensions that agree with a wide variety of build types from choppers to metric café motorcycles to Britbikes. It has a custom oil bag look that doesn't shout for attention. It's a highly functional reservoir, too, holding nearly three quarts of oil if the tank is assembled at full size, but it's a small enough in diameter to fit even in cramped spaces. The mild steel makes for easy drilling, cutting, and welding.

The tank includes a filler bung and bungs to accept 1/4" NPT fittings to plumb your feed line, return line, and vent. For a simpler installation, a vented filler cap is available separately. (We recommend using the remaining bung for an optional oil drain port.)

Mounting kits (also available separately) are a natural fit for 1982-2003 Harley-Davidson Sportsters that have been hardtailed using a TC Bros. rear section, but this tank and those kits are also very suitable for Harley-Davidson Big Twins and lots of other custom bikes with a traditional backbone and seat tube arrangement. 

We strongly recommend pressure-testing these oil bags after welding, fabrication, and mockup. This is standard procedure before applying any final coatings to ensure there are no leaks and proper clearance for fittings and hoses.
