With skyrocketing fuel prices theft is on the rise. The cost of the FSS 750 pre-vent security cap is small compared to the cost of the fuel in your tank. The FSS 750 pre-vent security cap is different from any other cap on the market, in that, the cap is secured to the filler neck by our unique patented “spinsecure” technology. When the cap is in secure mode the cap will freespin making it virtually impossible to remove.

Great item! Be sure to use threadlock as specified ...
Great item! Be sure to use threadlock as specified in the instructions. This is required because the thread type fpt and mpt and not npt. NPT self tightens as the male end enters the female end. FPT and MPT do not self tighten. Overall this is a great item and I would buy it again.

My husband says he is very happy with this purchase
My husband says he is very happy with this purchase. Our previous cap was allowing diesel to bubble out of the fuel tank, but this cap has stopped all of that. :)

Must have for aux tanks
Life saver. Love this product. Now I don't have to worry about idiots stealing my diesel from the bed of my truck when I'm in the city.

Great product.
This was just the ticket to replace an old lock for our fuel tank. The built in vent and swivel feature (once locked) assure protection.

Secure locking cap.
Works like a champ on my auxiliary tank and a very affordable vent to help on those warm days.
