Brand: Tilton Engineering
This is the same threaded plastic cap as supplied in Tilton 74-Series and 75-Series Master Cylinder Kits (Part Nos. 3505 and 3506). This cap fits all three sizes of Tilton Single-Chamber Plastic Reservoir Tanks with threaded necks (Part No. 3558, sold separately).
Sold individually. Two are pictured to show top and bottom views.
Note: Does not fit Tilton three-chamber reservoirs or aluminum reservoirs. Some very old Tilton plastic reservoirs used a 1/4-turn bayonnet-style cap and will not accept this newer threaded version.
