Ultra Clear Platinum Silicone Tubing 3/8 in ID x 1/2 in OD - Durable

In this review the Ultra Clear Platinum Silicone Tubing is evaluated for users who need a large, flexible, food- and medical-grade hose that performs across extreme temperatures. The bottom line: this 50 ft length of platinum-cured silicone is best for anyone replacing vinyl or rubber lines where clarity, flexibility and temperature resilience matter, because it is ultra clear, kink-resistant and rated for use from -100F to +500F while remaining safe for drinking water and approved for medical applications with proper sterilization.

Key Features

• Size and fit: The 3/8 in inner diameter and 1/2 in outer diameter provide a large bore that can stretch to fit over barbs up to 14 mm, making it easy to attach to common fittings.
• Material quality: Platinum-cured pure silicone delivers ultra clear, food-safe tubing suitable for drinking water and medical uses when sterilized properly.
• Temperature range: Insulates extreme heat and cold and remains usable across a wide span from -100F to +500F, so it works in demanding environments.
• Durability outdoors: UV resistant construction prevents deterioration outdoors and keeps the tubing flexible after extended exposure.
• Kink resistance: The silicone stays supple and resists kinking in bends, which maintains consistent flow for siphon and transfer applications.
• Made in the USA: Manufactured domestically by Cold & Colder, offering traceable production and consistent quality control.

Who It's For

This tubing suits homebrewers, sandblaster users needing a reliable siphon hose, laboratory technicians, and anyone running potable water lines or medical-device prototypes who requires food-safe silicone and wide temperature tolerance. The long 50 ft length is handy for extended runs without multiple joins.

It is less appropriate for users who need pre-assembled fittings or pre-molded connectors; installers who prefer rigid PVC or low-cost vinyl for one-off, short-term projects may find silicone more expensive than alternatives.

Pros & Cons

Pros

• High clarity and purity from platinum curing make it suitable for food and medical applications with proper sterilization.
• Excellent flexibility and elasticity allow it to stretch over barbs up to 14 mm while resisting kinks.
• Very wide operating temperature range and UV resistance support outdoor and extreme-condition use.
• Long 50 ft length reduces the need for joins and is convenient for larger runs.

Cons

• Some users may prefer greater optical clarity; opinions on how clear it appears are mixed among customers.
• It does not include fittings, so additional clamps or barbed connectors are required for many installations.
