We fabricate these ASA nipples (spools) from 304L stainless steel tubing and ASA flanges. ASA flanges are simple, sexed vacuum seals for HV applications; one flange is grooved to accept an o-ring while the other mating flange is smooth (flat).
ASA Nipples Feature:
- Half nipples feature one fixed flange (either flat or grooved)
- Reducer nipples adapt two different flange sizes
- Common lengths and tube diameters listed; contact us with your specific requirements
