So hard to find these large sizes of hose/barb caps. This was perfect for my application!

The 1/2" caps were a real pain to find as they kind of straddle the gap between vacuum caps and bypass caps, this kit was one of the very few places I could find them.

This is the only way to get 1/2" vacuums caps that I could find. Overall not bad for the price.

I bought these to cap all the openings on a SBC engine( carb fittings, water pump heater hose outlet, manifold vacuum port, etc). I am storing a fresh built 383 stroker I built for next spring and wanted to keep all openings from getting debris or critters.They seem to be made from a decent material.

Used two of these to close off the visibility spout on my yamaha Waverunner, fit perfectly. Thick rubber on the walls of these caps.

The bypass caps work great on my Chevy Suburban. I am so grateful that I found these. I repaired the faulty bypass cap on my vehicle and voila, no more leak. I am very happy! Thank you!
