obp Motorsport - Weld-On Aluminum Filler Neck with Cap, 40mm OD

This aluminum neck assembly is perfect for fabricating your own oil tank. The neck is also suitable for clamping into a molded spigot on a fuel cell bladder. An O-ring inside the threaded cap ensures a leak-free seal.

The neck measures 40mm (1.57") OD x 60mm (2.37") long without the cap. The cap measures 50mm (2") diameter, with machined scallops for easy gripping. An additional 19mm (3/4") clearance is required above the top of the neck to remove the cap. Coarse M40 x 2.0 metric threads allow quick on/off without cross-threading. Constructed of 6061 alloy.
