The grades
The figures below are the maker's published values.
| Product | What it is | Temperature range | Typical use |
|---|---|---|---|
| SELCO SG-900 | Silicone fluid thickened with complex lithium soap, NLGI 2 | −50 to 220 °C | General silicone grease duty across a wide temperature range |
| SELCO SG-1600 | Ultra-high-temperature silicone grease, NLGI 2 | −35 to 250 °C | Stenter chain bearings at low speed |
| SELCO SG-920 | Silicone vacuum grease | −50 to 200 °C | Vacuum joints, ground-glass fittings and sealing faces |
| SELCO SG-1491 | Dielectric red gel: synthetic base fluid with a silicate thickener | −20 to 250 °C | Electrical switchgear and connections |
SG-1491 is a dielectric gel on a synthetic base fluid; it is listed here because buyers ask for it alongside silicone greases. SELCO also makes two silicone oils, SELCOSIL-350 and SELCOSIL-1000.

Limits to know before you order
- SELCO does not make a PFPE grease. For true high-vacuum or oxygen service we quote a PFPE grease from a manufacturer that makes one.
- None of these four products is NSF registered. For food-contact areas see our NSF H1 food-grade lubricants.
- The maker does not publish full ASTM test tables on its public pages. We obtain the data sheet for each grade from the maker and send it with the quotation.
Documents and supply
The maker's data sheet and safety data sheet go with the quotation, and the maker's batch certificate with supply where one is issued. We quote on working days, usually the same day. Stocked items are dispatched within 2 working days from Secunderabad; other grades are supplied to order, with the lead time stated on the quotation. Transit is 48–72 hours in South India and 5–7 days elsewhere. Payment is in advance against a proforma invoice, and GeM orders follow GeM terms. Every order carries a GST tax invoice. Prices are on request: send the product, pack size and quantity and we quote.
For high-temperature, moly and high-speed greases, see the SELCO synthetic grease range.
