The special seals are rated at -40 degrees F and they're automatic in that it only requires one hand to push and lock the plug into place. The release, simply pull back the sleeve. 1/4 inch Male NPT threads. It is made of aircraft aluminum with a hard anodized finish for durability and light weight.
