Keep your 510 threaded RDAs or tanks cooler simply by adding our ingenious PEI insulation spacer.

Keep your 510 threaded RDAs or tanks cooler simply by adding this insulation spacer to your ecig build. Made from polyetherimide (PEI) thermoplastic, often referred to Ultem®, which is widely used in vaping because of its very high heat tolerance and good chemical inertness.

Suitable for use with most mechanical/competition mods but will only work with box mods that have a spring loaded battery contact with at least 1 mm of travel. Compatible with most atomisers and tanks that use the standard 510 thread, quick and easy to fit. Choose the size closest to or smaller than the diameter of your tank.

Fitting Instructions

Simply place the spacer over the screw threads of your tank and then fit onto your mod or battery as normal. Screw on firmly but do not over tighten.
