Product Overview
A vacuum-valve order needs more than a general high-vacuum description. Gas composition, required pressure conditions, cleanliness, temperature and acceptance testing all affect selection. Fluororubber is the confirmed seal description; no particular brand, compound grade, ultimate vacuum or helium leak rate is implied.
Selection and Ordering Notes
- Identify the ISO flange type, nominal size, mating hardware and available installation length.
- Provide gas composition, required pressure conditions, temperature and cleaning or bakeout requirements.
- Request the actual fluororubber compound and complete wetted-material specification.
- Specify operation, acceptance-test method and any required leak or vacuum performance before ordering.

Frequently Asked Questions
Will the ISO flange fit the vacuum fittings already installed?
Send the existing flange family, size and mating connection details. Obtain the selected valve drawing and hardware requirements before assuming that every ISO vacuum connection is interchangeable.
Which fluororubber seal compound is included?
Fluororubber sealing is confirmed, but the exact compound and brand must be identified in the quotation. Supply the gas, temperature and cleaning conditions so the proposed seal can be reviewed.
What vacuum or leak-rate performance can I specify?
State the actual system requirement and test method and request confirmation for the quoted valve. No numerical vacuum level or leak-rate guarantee should be derived from the product name or seal material alone.
