Fit perfectly
Truly impressive, bought these and a set from a us boat supplier a thermostat made in the USA . They came with the gasket separate . I could not figure out how to put it together . I used these in my mercury optimax 135 hp . They fit perfectly and appear to be working great at a quarter the cost .

High-Quality 12 AWG Silicone Wire — Perfect for Battery Projects
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
I bought the BNTECHGO 12 Gauge Silicone Wire (10 ft red and 10 ft black) to wire my battery power box, and it has worked flawlessly. BNTECHGO wire has always been reliable for me, and this set is no exception — very flexible, durable, and easy to work with. I’ve purchased numerous other gauges and colors from BNTECHGO, and I continue to be very happy with the quality. I would definitely buy again.
Important Note: The amperage rating depends on your wire gauge and your specific application. Make sure to size your wire appropriately based on the current requirements of your project to avoid overheating or damage.
Potential Uses:
Wiring battery power boxes or DIY power systems
Automotive, RV, or marine electrical projects
Solar panel or off-grid power setups
Ham radio or portable electronics wiring
LED lighting and audio equipment wiring
Hobby electronics and custom projects
Key Features:
12 AWG stranded tinned copper for excellent conductivity
Silicone insulation for extreme flexibility and heat resistance
10 ft red and 10 ft black for positive/negative wiring
High-quality, durable construction for long-lasting use
Flexible enough to route through tight spaces without kinking
Resistant to high temperatures, abrasion, and bending
Disclaimer: This review reflects my personal experience only and is not professional electrical advice. Always follow proper safety procedures and ensure your wire is properly sized for your application’s voltage and current requirements.

Very high quality for a fair price!
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
I just can't say enough good about this wire! It's really high quality stuff, so much so that I was impressed enough to write another review and buy more! Yeah it's really that good considering you don't see this type of wire around much. Good stuff!
