** Maximum working pressures do not vary with temperature.

Maximum Working Pressures (MWP)

The lesser of the MWP for the hose and the MWP of either of the end fittings.

Temperature Limitations

Usable from -73˚C, -100˚F up to +204˚C, +400˚F.

Vacuum Limitations

Pharmaline N and X hose is usable at vacuum to -0.9bar up to 150˚C, 302˚F.

Rolling U Test for Flex Life

More than 15 x the flex life to failure compared with other types of rubber covered, smoothbore PTFE lined hose products.

Flexibility

Much less force to bend than any other equivalent smooth bore PTFE lined hose product.

Kink Resistance

Much more resistant to kinking than any other equivalent smooth bore PTFE lined hose product.

Soakable

Pharmaline N hoses are soakable.
