⚡ At a Glance
- • Connection Reliability: Precision threads combined with a rubber washer produce tight, leak-resistant joints
- • Best for: Fuel systems, oil cooling, DIY automotive engine tuning and gauge connections
- • Not ideal for: Applications requiring thread sizes other than M12x1.5 or 1/8 NPT
Stainless steel construction with precision-formed threads and an included rubber washer ensure a durable, sealed connection. Suited to oil, fuel, water and temperature pressure gauge fittings in automotive contexts.
Leak-resistant joins - thanks to rubber washer and precision threads
The adaptor uses a moulded rubber washer seated against the female 1/8 NPT face, while the male M12x1.5 thread is cut to close tolerances to ensure correct engagement. Precise thread form reduces thread play and helps the sealing surface compress the washer evenly.
Reliable sealing reduces the chance of fuel or oil seepage during operation. That makes the adaptor suitable for visible plumbing runs and gauge fittings where a tidy, tight connection is needed.
Corrosion resistance - with stainless steel material
Manufactured from stainless steel, the fitting resists oxidation and surface corrosion that can affect soft alloys and plated fittings. The material choice supports long-term exposure to oil, fuel and moisture without rapid deterioration.
Longer service life and less maintenance in workshop environments prolongs time between replacements. Users working on vehicles or outdoor systems benefit from reduced corrosion concerns.
Easy installation and removal - with standard thread forms and included washer
Male M12x1.5 and female 1/8 NPT threads match common automotive and gauge fittings, allowing straightforward engagement by hand or with a small spanner. An included washer removes the need to source a separate sealing part during installation.
Finger-tight installations are practical for quick sensor swaps or gauge fitting, and the adaptor can be removed easily if adjustments are needed. That convenience helps when testing or reconfiguring lines during tuning work.
