Product Details

The GReddy 11900651 is a precision-engineered vacuum hose union fitting designed for high-performance applications. This straight fitting connects an 8mm vacuum hose nipple to a 1/8 BSP (British Standard Pipe) threaded port, commonly found on Japanese performance vehicles and aftermarket components.

Key Features:

  • Brass construction with chrome plating for corrosion resistance and durability
  • 8mm hose nipple diameter for secure vacuum line connection
  • 1/8 PT thread (1/8 BSP/BSPT in USA terminology)
  • Straight configuration for easy installation
  • Precision-machined threads for leak-free seal

This fitting is commonly used with GReddy boost controllers, sensors, oil cooler adapters, and other vacuum-operated performance components. The 1/8 PT thread standard is prevalent on Japanese performance parts and differs from the 1/8 NPT standard more common in the USA. GReddy part number 11900651 is listed as Hose Union No. 13 in the manufacturer's catalog.

ORDER HELLA SUPERTONES, SHIPPING PRICE WAS VERY REASONABLE, AND SHIPPED TIMELY. HIGHLY RECOMMEND THEM!!

seemed a bit hard to find products, but the prices were great and delivery prompt

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

Ease to pay with Amazon was great.

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

The correct product that I ordered, and easy to find through there web site.thanks

Cheapest prices I found online! Ordered at 4:30 on a Thursday afternoon and had 'em waitin' on my doorstep by SATURDAY!
