What is PTFE tubing used for?
PTFE tubing is most widely used as laboratory tubing and for applications where chemical resistance and purity are essential. PTFE has a very low coefficient of friction and is one of the most “slippery” substances known. We offer a broad range of sizes which can be used with standard compression fittings.
Is PTFE tubing rigid?
PTFE is not prone to distortion, but can kink relatively easily. This is semi-rigid tubing so is not suitable for use on peristaltic pumps.
Is PTFE tubing clear?
*Manufactured by Fluorotherm™ in the USA, PTFE tubing is semi-transparent in color and FDA approved.
Is PTFE bendable?
“Unlike the rigidity of tubing and pipe, it can be bent without the need of tube benders or additional fittings.”
What is an fitting size?
Each AN size refers to the outer diameter (o.d.) of the tube, or inner diameter (i.d.) of the hose that it’s used with. The numbers assigned equal the size in 1/16 inch increments….Plumbing Basics – AN Fittings & Hoses.
| AN Size | Hose i.d. – Tube o.d. | SAE Thread Size |
|---|---|---|
| -28 | 1 3/4 in. | 2 1/4 in.-12 |
| -32 | 2 in. | 2 1/2 in.-12 |
Is PTFE the same as silicone?
PTFE is hydrophobic, meaning it repels water, so lubricants containing it are effective in damp conditions. Silicone lubricants make surfaces ultra-slippery while repelling water. They’re safe to use on rubber, plastic, wood and metal.
Why is PTFE called Teflon?
PTFE is the shortened name of the chemical polytetrafluoroethylene, and Teflon is the trade name of the same polymer. If you are looking for a highly flexible, non-stick material that is chemical, electrical and thermal resistant, look no further than PTFE.
How flexible is PTFE?
PTFE (polytetrafluoroethylene) is the most flexible of all fluoropolymer tubing. It also has the broadest temperature range (-400°F to 500°F) and can resist highly corrosive liquids and gases even at elevated temperatures.
Is Teflon tubing the same as PTFE?
Essentially, the only difference lies in the name. PTFE is the shortened name of the chemical polytetrafluoroethylene, and Teflon is the trade name of the same polymer. If you are looking for a highly flexible, non-stick material that is chemical, electrical and thermal resistant, look no further than PTFE.
What size is an fitting in inches?
Plumbing Basics – AN Fittings & Hoses
| AN Size | Hose i.d. – Tube o.d. | SAE Thread Size |
|---|---|---|
| -10 | 5/8 in. | 7/8 in.-14 |
| -12 | 3/4 in. | 1 1/16 in.-12 |
| -16 | 1 in. | 1 5/16 in.-12 |
| -20 | 1 1/4 in. | 1 5/8 in.-12 |
Is PTFE better than rubber?
Polytetrafluoroethylene also has less surface friction than rubber, which means that flow can be improved by using PTFE hoses. While rubber is prone to break down at extreme temperatures, PTFE is highly temperature resistant, making it ideal for all kinds of industries.
Are PTFE and an fittings the same?
Cutting PTFE chose is no different than cutting rubber hose, but AN fittings use a brass “olive” (or ferrule) that crushes to provide the seal at the fitting/hose mating point.
Is PTFE safe for rubber?
Synthetic Grease Safe for all O-Ring and Seals . . . Contains PTFE (PolyTetraFluoroEthylene) water resistant sealant, rubber-safe, silicone-safe synthetic grease.
Does silicone bond to PTFE?
The trick is that the PTFE and silicone surfaces are not held together by a chemical adhesive. Rather, zinc oxide nanocrystals (ZnONC) with the general aspect of a caltrop or tetrapod allow PTFE and silicone surfaces to be “stapled” together, forming a strong mechanical bond without any chemically-driven bond at all.
