Dairy Processing Seals, O-rings and Gaskets

Typical sealing concerns in dairy processing include:

• Milk fat and cream, which can swell or soften some elastomer compounds
• Homogenisers running at high pressure, where plunger seals and valve seats wear steadily
• HTST and UHT plate or tubular heat exchangers, with gaskets that face hot product on one side and hot water or steam on the other
• Lobe pumps handling viscous yoghurt, cream and cheese curd, where seals must cope with thick product and frequent cleaning
• Daily CIP with caustic and acid, which ages O-rings in valves, fittings and filler heads
• Powder plant equipment where dust and heat affect seals on rotary valves and fans

These product families are commonly enquired about in this sector. Open any page for sizes, materials and buying options.

• Mechanical Seals: Seals for hygienic centrifugal and lobe pumps.
• Metric O-rings: O-rings for valves, fittings and filler heads.
• O-ring Kits: Kits for routine valve and filler maintenance.
• PTFE Gaskets and Seals: PTFE parts for demanding chemical and temperature duties.
• Rubber Gaskets and Elastomer Products: Elastomer gaskets and moulded parts.

Dairy duties are usually decided by the combination of fat content, temperature and cleaning chemicals. EPDM is often considered for hot water and many CIP solutions, while fatty products may call for other compounds such as FKM or specific food-grade grades. These are typical starting points only; always confirm against the manufacturer's data for your application.

All product-contact seals, O-rings and gaskets require technical review and the correct certification documents before supply.

Information that speeds up a correct recommendation:

• Product (milk, cream, yoghurt, cheese, whey) and fat content
• Process and CIP temperatures and chemicals
• Equipment make, model and serial number
• Whether the part is in product contact

For homogenisers, separators and pasteurisers, the machine make, model and serial number are the fastest route to correct parts. Send photos of worn seals with measurements where the parts list is not available, and we will route uncertain items to technical review.

If you are unsure what you have, start with find my seal, upload a drawing, or read about our technical support.

Dairies run tight schedules, so planned kits for each pump, valve type and filler reduce downtime at service intervals. We can quote kits as lists and discuss inventory management and supply agreements for regular items. Availability and documentation are confirmed per enquiry.

Globseals offers three ways to buy: buy online where a confirmed price is shown, request a quote for custom, bulk or unpriced items, or ask for technical review when identification is unresolved. Call 011 079 6033, WhatsApp 079 508 0989 or email info@globseals.com.
