The Chase Bays Differential Vent & Catch Can is the culmination of thousands of laps in our drift and race cars that often pushed fluid out of the differential. This got very smelly diff fluid that is difficult to clean all over axles and rear suspension components. Under heavy use this is common and extremely annoying, so we had to develop a solution. This is also beneficial to give the diff more venting ability. The factory diff outlet or vent is commonly too small for the heavy abuse we throw at it which can create internal pressure and premature wear.

The Diff Vent Catch Can was an easy lateral integration to our product line, this is our extremely developed Oil Catch Can with a smaller Inlet fitting and our Vent to Atmosphere SS 10AN ORB Filter on the Outlet. More of the nitty gritty internal design details and specifications can be found in the highlighted link.

Our catch can is machined from 6061 aluminum, bead blasted, then Hard UV-Proof Anodized Signature Chase Bays Black. The top and bottom are threaded together and sealed with an O-Ring for a leak proof connection that is safe for the most extreme pressurized applications. All hardware is stainless steel. The 10AN ORB inlet and outlet are both on the top for a seamless look and easy routing. Five different bracket types are offered to make mounting easy.

Air Oil Separation
The inlet is equipped with a stainless steel mesh filter for the best possible air, oil, and water condensation separation before it even enters the tank. Once the oil has passed through the filter, we have created the highest level of Oil Separation Baffling from the Outlet to vent to atmosphere without making a mess.

Oil Level and Drain
An integrated mini Chase Bays Reservoir Cap Style Dip Stick with a notch shows when the oil is ready to be drained, although rare being used as a Diff Vent. The Dip Stick is knurled for easier gripping. When the oil is ready to be drained, there is a 4AN ORB port on the bottom of the Can or the lower housing can be removed. If that plug is inaccessible where mounted or we recommend our Oil Catch Can Drain Kit with Petcock.

Fittings
Inlet and Outlet threads are 10AN ORB, and we have drop down options for 3/8 Push-On Hose or 4AN which are optimal size for venting the differential pressure.

Mounting
We require mounting the inlet at least equal height to the vent or higher for proper function. The back side of the catch can has two M8x1.25 threaded holes with included Stainless Allen Head Hardware for easy mounting. It is available with five different bracket design OPTIONS making installation on any chassis a breeze, see photos below for each bracket type. One included per purchase.

Dimensions and Capacity
The Catch Can Dimensions are 5"x3" without fittings and 6.5"x3" with. The oil capacity before its air/oil separation capabilities are void is 8 fluid ounces (0.25 quart).
