Brand: Tilton Engineering
This cap fits all three sizes of Tilton Single-Chamber Plastic Reservoir Tanks with threaded necks (Part No. 3558, sold separately). Note that some older Tilton reservoirs used a bayonnet-style cap and will not accept this newer threaded version. This is the same threaded plastic cap as supplied in Tilton 74-Series and 75-Series Master Cylinder Kits (Part Nos. 3505 and 3506).
Sold individually. Two are pictured to show top and bottom views.
Note: Does not fit Tilton three-chamber reservoirs or aluminum reservoirs.
