Chemical Resistant, High Temperature PTFE Hose Asselies

Both of these hoses are constructed of a natural FDA compliant PTFE core tube and reinforced with a 304 stainless steel braid. The silicone jacket on the 919J PTFE hose only reduces the lower operating temperature (-40°F to +450°). The polyurethane jacket on the 919U hoses reduces the minimum and maximum temperature range (-40°F to +275°F).

What is PTFE? - AFT Fluorotec

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of appliions, though it''s perhaps best-known for its non-stick properties.

PTFE meaning. Pros and Cons of PTFE Coating explained by

11/1/2019· PTFE Coating – meaning. PTFE coating is the process of coating items in PTFE. This is primarily done with two coats (a primer & a top coat). The PTFE coating is applied to areas where either a low friction, a corrosion-resistant or a dry lubricant is required. To coat a product with PTFE, it will need to be prepared first of all.

Chemical resistance FEP - Polyfluor

Chemical resistance FEP. Although FEP is similar to PTFE, there are a nuer of important differences. It has a slightly higher coefficient of friction, lower continuous working temperature and is more transparent than PTFE. FEP has a better gas and vapor permeability and outstanding UV transmission values.


PTFE hoses are chemically resistant to all CIP, SIP and autoclave systems. If electrostatic charges develop during cleaning, which may happen when solvents, steam or hot water are used, a PTFE anti-static should be adopted.

PTFE hose and Permeation. A PTFE molecule is a long chain of carbon atoms surrounded by fluorine atoms. Each carbon atom has two fluorine atoms bonded to it. As a Carbon Fluorine bond is extremely strong and each carbon in the chain has two Fluorine atoms bonded to it, this gives PTFE a tough carbon backbone surrounded by a protective sheath of

Polytetrafluoroethylene - Wikipedia

or PTFE hose is too small, the inner hose wall is likely to ‘kink’, restricting fluid flow, severely weakening the hose and making it liable to fail prematurely, even if the hose is later ‘un-kinked’. Both rubber compound and PTFE hoses can take on a permanent ‘set’ or shape (become less flexible) after some time in service. The inner liner
