      Great Petcock for hard to fit/hidden fuel line connection

      i have a tank where any standard petcock would be interfered with by the CR carbs. this solution gave me room to run the line and eliminate this interference. also, looks very cool inline.

      Badass little piece

      This thing looks trick and can either be tucked away neatly or have it visible and show it off. Either way, super cool

      Perfect little unit

      I bought the prism valve but it wasn’t close to fitting. Finally was able to get one of these while they was in stock . Fits great. Looks cool with my assortment of lowbrow parts only bike

      Get what you pay for

      I bought quite a few in line petcocks before this one. They all had terrible flow. This petcock is very well built and functions as good as the price tag suggests

      Inline Brass Petcock

      Just installed the brass inline petcock on my 71 Triumph cafe' racer and the look is suttle and clean. I need one more petcock, but the order page said "bummer out of stock." I hope to purchase one more petcock as soon as they come in.

      a quality product

      i havein't yet hooked it up. I will be happy if it has adequate flow for my 1000cc bike/ the hose connections are 7mm/5/16, the openings on the petcoclk are just under 1/4" time will tell. it is a litle work of art, beautifully made.
