What to know before buying

Listing details to confirm

The listing's 12MM size does not specify clearly whether it refers to barb diameter or hose inner diameter. Measure the hose and confirm fit before purchase. The listed temperature range is given with inconsistent Celsius and Fahrenheit endpoints, so confirm the applicable range and suitability for your medium and pressure. The claimed leak-proof performance is not independently established. A hose clamp is not included.
