Replacement Small Frame Turbo Drain O-Ring

Don't let a worn drain seal turn into a costly oil leak. This small frame turbo drain o-ring replacement helps keep your build tight and running clean.

Why This O-Ring Belongs in Your Maintenance Kit

Direct-Fit Replacement

Sized specifically for small-frame turbos, including BSI Inc. / True North Turbos units. No trimming, stretching, or hoping a bulk bag of assorted o-rings has the right one buried inside.

Stop Leaks Before They Start

A degraded turbo drain seal is one of the most common sources of oil seepage in any turbo build. Swapping this o-ring at the first sign of weeping, or as part of routine maintenance, can save you from chasing a much bigger mess later.

Turbo oil drain environments are hard on seals, with high heat, constant oil exposure, and pressure cycling. This o-ring is engineered to hold up where generic hardware-store substitutes fall short.

At a fraction of the cost of a full turbo service, this is the kind of preventative maintenance item worth having on the shelf. Installation is straightforward, with no special tooling required.

Backed by BSI Inc.
