LONDON, July 6 (Reuters) - Russian Urals crude oil came under pressure on Monday as refining margins stayed weak and outright values for all grades slipped, traders said.

URALS

* In the north, a couple of refiners were reported to be uncovered and looking to buy Urals cargoes for mid-July but the best bid within the afternoon trading window was from Glencore for July 16-20 at dated BFOE minus 35 cents, 45 cents better than its first indication.

* The best NWE Urals seller showing within the window was Gunvor at dated BFOE plus 5 cents for July 27-31, down from an initial offer at dated plus 20 cents. Traders said sellers were likely to be willing to consider dated minus around 10 cents but no indications were seen from either side of the market at this level.
