Ultra Clear Platinum Silicone Tubing 1/2 in ID x 5/8 in OD - High Temp

In this review the Ultra Clear Platinum Silicone Tubing is evaluated for larger plumbing, lab and hobby projects where clarity, flexibility and heat resistance matter most. It is a 50 ft length of platinum cured silicone with a 1/2 in inner diameter and 5/8 in outer diameter, made to a firmer Shore-A 70 so walls resist collapse. The bottom line: this tubing is best for users who need a durable, food and medical grade hose that stays flexible from extreme cold to extreme heat and resists kinking and UV damage.

Key Features

• Diameter and fit: The 1/2 in ID and 5/8 in OD provide a roomy flow path and slip-fit over common hose barb fittings for secure connections.
• Material quality: Platinum cured pure silicone offers ultra clear appearance and food and medical grade safety when properly sterilized for drinking water and other sanitary uses.
• Temperature range: Usable from -100F to +500F so the tubing works for cryogenic to high heat applications without losing flexibility.
• Durability: Manufactured with a harder Shore-A 70 wall to resist collapse while remaining supple and kink-free through repeated use.
• Outdoor resilience: UV resistant construction keeps the tube from deteriorating outdoors, making it suitable for long-term external installations.
• Made in the USA: Produced domestically by the brand, which may matter for quality control and sourcing preferences.

Who It's For

This tubing is aimed at hobbyists, technicians and small-scale industrial users who need a larger bore silicone hose that maintains shape during siphoning, sandblasting siphon setups, beverage lines or lab rigs. The firmer wall makes it a good choice where slippage or collapse under suction is a concern.

Those who need absolute optical clarity for display applications or who require a softer, more compressible tubing for tight fittings should look elsewhere; vinyl or softer silicone variants will be easier to stretch over very small barbs or provide clearer visual transparency in some subjective comparisons.

Pros & Cons

Pros

• High material quality that is food and medical grade when sterilized, suitable for potable water and sanitary uses.
• Wide temperature tolerance and UV resistance mean long life across extreme environments.
• Stiffer wall (Shore-A 70) prevents collapse and stays flexible for siphon and hose-barb applications.
• Good value for a 50 ft length compared to short sample runs.

Cons

• Some customers note the visual clarity is not perfectly glass-clear compared to other materials, so appearance expectations should be managed.
• The firmer wall can be less forgiving when needing to stretch over unusually small fittings.

It represents solid value for plumbing, lab and siphon uses where material safety and durability matter more than perfect optical clarity.

Frequently Asked Questions

Is this tubing safe for drinking water?
Yes, the platinum cured silicone is food safe and suitable for drinking water when properly cleaned and sterilized before use.

Will the hose collapse under vacuum or siphon use?
The tubing is made with a harder Shore-A 70 wall to resist collapse and performs well on hose barb fittings in siphon and suction applications.

Can it be used outdoors long term?
Yes, the material is UV resistant and formulated to remain flexible and durable after years of outdoor exposure.
