What are chemical resistant oil seals?
Chemical resistant oil seals are rotary shaft seals made from elastomers such as FKM (Viton), PTFE, EPDM or FFKM that tolerate contact with aggressive fluids — acids, solvents, process chemicals or hot oils — without swelling, cracking or losing lip contact. They keep lubricant inside the housing and contaminants out where a standard nitrile seal would degrade quickly.
Which material is best for chemical resistant oil seals?
There is no single best material. PTFE resists the broadest range of chemicals; FKM suits hot oils, fuels and many aggressive fluids; EPDM handles water-based and polar fluids; FFKM serves the most demanding combined chemical and temperature duty. Selection depends on the chemical, its concentration, the temperature and the shaft speed.
Are Viton oil seals suitable for chemicals?
FKM (Viton) oil seals resist many oils, fuels and selected aggressive chemical environments, and hold up at high temperatures where nitrile fails. They are not universal, however — certain solvents, ketones and hot water or steam attack FKM. Compatibility must always be checked against the actual chemical and working conditions.
Are PTFE oil seals suitable for chemical pumps?
Yes — PTFE oil seals are a common choice for chemical pump shafts because PTFE resists a very wide range of chemicals and runs with low friction. They need proper shaft finish and correct spring loading, and they suit applications within their temperature and pressure limits. AnantaVenture confirms suitability against the pump type, fluid and duty before recommending PTFE.
What sizes of chemical resistant oil seals are available?
Seals are sized by shaft inner diameter (ID), outer diameter (OD) and width in millimetres. Standard representative sizes from 10 mm to 120 mm shaft diameter are listed in the catalogue on this page, and additional standard and special sizes can be discussed. Availability in a specific chemical-resistant compound is confirmed against your requirement.
What is the price of chemical resistant oil seals?
Prices depend on size and material. This page shows indicative OD-wise reference rates for general Blowsom oil seals; chemical-resistant FKM and PTFE seals are quoted separately on request because their material-specific rates differ from general-purpose seals. Confirm the latest price and stock with AnantaVenture before ordering.
How do I select the correct oil seal for a chemical pump?
Start with the shaft diameter, housing bore and seal width, then identify the chemical being handled, its concentration and temperature, the shaft speed and any pressure in the chamber. Share these details — or the old seal — with AnantaVenture, and the team will confirm a compatible compound and size.
Can oil seals be customized according to machine dimensions?
Yes. Ananta Venture manufactures against requirement — share your shaft diameter, housing bore and width, a drawing, or simply send the old seal. Custom and non-standard sizes are discussed and confirmed for supply before production, including application-based compound selection.
Which industries use chemical resistant oil seals?
Chemical processing plants, petrochemical units, industrial pump and fluid handling equipment manufacturers, agitator and mixer builders, pharmaceutical and water-treatment plants, plus general industry wherever shafts run in aggressive or hot fluids instead of plain lubricating oil.
How can I order chemical resistant oil seals from AnantaVenture?
Call or WhatsApp +91 9211305366, email [email protected], or send your requirement through the contact page. Share the seal size (ID × OD × width), the chemical or fluid involved and the machine details — the team confirms material suitability, sizes, price and availability before dispatch.
