Bosch Copper Tubing Installation Kit for Mechanical Pressure & Boost Gauges — 72in Soft Copper with 1/8" and 1/4" NPT Fittings

This kit gives technicians and DIY enthusiasts the parts needed to route a durable copper line between mechanical gauges and engine ports. Built by Bosch — a brand known for precision engineering across automotive and industrial markets — the kit is intended to work with Bosch mechanical pressure and boost gauges. If your installation requires metric thread sizes, Bosch offers adapter kit SP0F000009 as a complementary option.

What components are included and why do they matter?

The kit contains soft copper tubing measured at 72 inches and a set of NPT fittings sized to match common gauge and engine ports. Soft copper tubing is flexible enough for routing yet rigid enough to resist kinking when properly bent, while the NPT fittings provide tapered threads for reliable sealing under normal gauge pressures.

• 72" of soft copper tubing for customizable routing
• 1/8" NPT gauge fitting for standard mechanical gauge connections
• 1/8" and 1/4" NPT engine fittings to fit common port sizes
• Compatible with Bosch mechanical pressure and boost gauges

How do I install the tubing with my mechanical gauge?

Installation involves cutting the copper tubing to length, flaring or bending as needed, and threading the correct NPT fittings into the gauge and engine ports. Use appropriate thread sealant or tape on tapered NPT threads to prevent leaks and ensure snug engagement without over-torquing fittings.

• Measure required length and cut with tubing cutter for clean ends
• Bend gently to avoid flattening; add a small flare if needed for fittings
• Apply thread sealant or PTFE tape to NPT threads before assembly
• Hand-start fittings, then snug with wrench; avoid excessive torque

Will this kit fit my vehicle or equipment?

The included 1/8" and 1/4" NPT fittings cover many common engine and gauge port sizes found in automotive, marine, and light industrial applications. If your application uses metric threads or a different fitting standard, use Bosch adapter kit SP0F000009 or check thread compatibility before installing.

• Fits many gauges and ports with 1/8" or 1/4" NPT threads
• 72" tubing allows flexibility for routing in tight or extended spaces
• Use SP0F000009 adapter kit for metric-threaded applications

How should I maintain the copper line after installation?

Copper tubing is low maintenance but benefits from periodic checks for secure fittings and corrosion, particularly in harsh or salt-exposed environments. Inspect the line for signs of leaks, dents, or vibration-driven wear and replace or re-route if damage is found.

• Check fittings and routing during routine service intervals
• Look for pinching, corrosion, or abrasion at contact points
• Replace tubing sections showing wear instead of patching

Who is this for: The Bosch SP0F000012 kit is aimed at mechanics, tuners, and vehicle owners installing or replacing mechanical pressure or boost gauges who want a reliable, ready-made copper tubing solution. It’s suitable for shop professionals and experienced DIYers who need standard NPT connections and a long run of soft copper tubing; those requiring metric fittings should add Bosch adapter SP0F000009.
