Manufacturing process
Production of Viton Ball combines cold isostatic/uniaxial compaction of engineering fluoropolymer powder with multi-stage thermal free-sintering. Compaction loads are held under precise electronic dwell timing to bleed out microscopic air pockets. Sintered blanks are then transferred to climate-controlled CNC turning and milling centers to machine critical drawing features.
Material selection notes
Manufactured from engineering fluoropolymer, this component combines high tensile strength (20–35 MPa) with excellent chemical and weathering resistance. The material maintains flexibility at low temperatures while providing stable compressive support under high system pressures.
How to specify your order

Quality checks and inspection
Inspection protocols for Viton Ball encompass dimensional coordinate verification, density testing, sphericity profilometry on balls, and visual surface inspection under optical magnification. Full mill test certificates (MTR) accompany all shipments.
Ordering and export documentation
Domestic Viton Ball orders ship with GST invoice and e-way bill where applicable. Export orders include commercial invoice, packing list, and certificate of origin from our IEC-registered works. Material certificates and dimensional reports attached for qualified pharmaceutical and OEM shipments Contact info@hemsun.com or sales@hemsun.com with your balls specification.
Export packing and lead time
International distribution of Viton Ball is supported with multi-currency commercial terms, export shipping documentation, and protective multi-layer packaging to ensure components arrive in pristine condition worldwide.
Storage and handling
Storage and operating notes for Viton Ball: Keep parts in sealed packaging at ambient room temperature. During equipment overhaul, inspect sealing lips for particulate embedding and replace components showing mechanical wear.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Diameter and sphericity are verified on calibrated gauges and the achieved grade is recorded on the inspection report; sintered density is checked per ASTM D792. A mill test certificate ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
Frequently Asked Questions
What is the largest Viton Ball you manufacture?
We manufacture Viton (FKM Fluoroelastomer) Balls up to 310mm diameter.
When should I use Viton Ball instead of NBR Ball?
Use Viton Ball when: service temperature exceeds +120°C (Viton goes to +200°C vs NBR's +120°C), process media includes aromatic solvents, esters, or ketones that attack NBR, or process media contains aggressive acids or oxidizers. NBR is preferred for standard oil and fuel service at moderate temperatures where cost is a factor.
Are Viton Balls suitable for automotive and aerospace fuel systems?
Yes. Viton (FKM) Balls are widely specified in automotive high-performance fuel system check valves, turbocharger lubrication check valves, and aerospace jet fuel system check valves — combining broad fuel resistance with high temperature capability up to +200°C.
