Choosing the compound
The choice depends on two things: how hot the joint runs, and whether copper is allowed on the metal or near the process. The values below are the maker's published figures.
| Product | Type | NLGI | Temperature range | Use it when |
|---|---|---|---|---|
| SELCO AS | Copper-based anti-seize compound | 1.5 | −10 to 1100 °C | Carbon-steel fasteners in hot zones. The maker states it is free from lead, graphite and aluminium and does not carbonise at high temperature. |
| SELCO SG-660 | Synthetic PTFE paste, metal-free | 2 | −25 to 450 °C | Stainless steel, or anywhere copper contamination is not acceptable. |
| SELCO SG-650 | Molybdenum disulphide assembly paste | 0 | −25 to 450 °C | Press fits, splines and heavily loaded sliding surfaces during assembly and running-in. |
SELCO AS is also supplied in molybdenum disulphide, graphite and zinc based versions. Tell us the fastener metallurgy and the temperature and we specify which.

Typical uses
- Cement plants: SELCO AS on kiln, cooler and preheater fasteners.
- Steel plants: SELCO AS on hot-strip mill and continuous-casting fasteners.
- Refineries and petrochemical plants: SG-660 on valve stems and instrument connections where copper is not acceptable; SELCO AS on carbon-steel hot-zone fasteners.
- Pharma and food plants: SG-660 on equipment outside the incidental-contact zone.
What SELCO does not make
SELCO's maker does not make a nickel, aluminium or ceramic anti-seize, and no SELCO anti-seize is NSF registered. Where a nickel compound is specified for stainless or high-nickel fasteners, we quote it from a manufacturer that makes one. We do not substitute copper.
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.
The full range, including the silicone vacuum grease and the gear-oil additive, is on our SELCO anti-seize page.
Frequently Asked Questions
Which anti-seize should I use on stainless steel fasteners?
Use SELCO SG-660, a metal-free synthetic PTFE paste rated −25 to 450 °C, where copper is not acceptable. If your specification calls for a nickel compound, we quote one from a manufacturer that makes it; SELCO does not.
What temperature is the copper anti-seize rated to?
The maker rates SELCO AS from −10 to 1100 °C and states that it does not carbonise at high temperature.
Is there a food-grade (NSF H1) anti-seize in this range?
No. No SELCO anti-seize is NSF registered. SELCO's NSF H1 products are the SF-330 oil, the SG-330 grease and the SF-330 aerosol.
What is the difference between anti-seize and assembly paste?
Anti-seize stops threads and joints from welding together in service so they can be dismantled later. An assembly paste such as SG-650 lowers friction while parts are fitted and run in.
How do I get a price?
Prices are on request. Send the product, pack size and quantity and we quote on working days, usually the same day.
