FREQUENTLY ASKED QUESTIONS ABOUT CLEANED & BAGGED
-
What are cleaned and bagged press fittings?
Cleaned and bagged press fittings are precision-cleaned components that are individually packaged after cleaning to help protect them from contamination during transportation, storage and jobsite handling. Viega Cleaned & Bagged fittings combine this controlled preparation with press technology for high-purity and controlled-environment applications.
-
What applications are Viega Cleaned & Bagged fittings designed for?
Viega Cleaned & Bagged supports high-purity and controlled applications including pharmaceutical manufacturing, automotive and specialty paint facilities, research laboratories, battery manufacturing, semiconductor, advanced and precision manufacturing and industrial gas distribution.
-
Can Viega Cleaned & Bagged fittings be used for high-purity gas systems?
Yes. Viega Cleaned & Bagged components are designed to support gas systems requiring purity levels up to 99.9999%, or 6N, depending on the application and system requirements.
-
Are Viega Cleaned & Bagged fittings cleaned for oxygen service?
Yes. Viega identifies select ProPress Cleaned & Bagged products as cleaned for oxygen service. Viega tests to ASTM G93 and CGA G-4.1 as its primary cleaning standards. Application requirements should be confirmed against current Viega technical documentation before specification or installation. These fittings are not approved for medical gas applications governed by NFPA 99 or for FDA food-contact applications.
-
Do Viega Cleaned & Bagged fittings require field cleaning before installation?
Viega Cleaned & Bagged components are precision-cleaned and individually bagged before arriving at the jobsite, eliminating the need for field cleaning. Components should remain protected and be handled according to Viega installation requirements.
-
What cleanliness standards are referenced for Viega Cleaned & Bagged products?
Viega tests Cleaned & Bagged products to ASTM G93 and CGA G-4.1 as its cleaning standards. Additional industry standards referenced in connection with Viega's cleaning requirements and controls include CGA G-7.1, MSS SP-138 and ISO 8573. Cleaning is performed in an ISO Class 8 cleanroom or better.
-
How long do Viega Cleaned & Bagged fittings remain clean in the bag?
Viega states that Cleaned & Bagged fittings retain their cleanliness for two years while maintained in their sealed packaging, providing flexibility for storage and project scheduling.
-
Can existing Viega press tools be used with Cleaned & Bagged fittings?
Cleaned & Bagged installation follows standard Viega press procedures and is compatible with existing Viega press tools where specified. Installers should reference the applicable installation instructions and tooling requirements for the specific product and size.
-
Are Viega Cleaned & Bagged fittings approved for medical gas systems?
No. Viega states that Cleaned & Bagged products are not intended for medical gas systems governed by NFPA 99. They are also not approved for FDA food-contact applications. They are positioned for industrial and other qualifying high-purity applications.
-
What materials and product types are available Cleaned & Bagged?
Viega's Cleaned & Bagged portfolio includes select ProPress copper and stainless steel fittings and valves, along with additional products identified within the Cleaned & Bagged portfolio. Specific availability should be confirmed through current Viega product documentation.
-
Is Cleaned & Bagged the same as Cleaned for Oxygen Service (CFOS)?
These terms refer to the same category of precision-cleaned components designed to remove contaminants that could affect high-purity gas systems. Viega uses "Cleaned & Bagged" as its primary designation because the cleaning standards apply across a broad range of high-purity industrial applications – not exclusively oxygen service. Cleaning is tested to ASTM G93 and CGA G-4.1, which are widely recognized oxygen-service and high-purity cleaning standards.
