Are you an authorized Duncan Engineering dealer?
Yes - we have been an authorized dealer for Duncan Engineering (formerly Schrader Duncan) since 2001, and stock genuine Duncan pneumatics ex-stock from our Vadodara warehouses.
Do you supply the older "Schrader Duncan" branded parts?
Schrader Duncan Ltd renamed to Duncan Engineering Ltd in December 2016 - same manufacturer, same Ranjangaon facility, no change in form, fit or supply. If your nameplate or old drawing says Schrader Duncan, send the part number and we will match it to the current Duncan range.
Can you supply an equivalent if a Duncan part is discontinued or lead time is too long?
Yes. Where a Duncan line is discontinued or its lead time doesn't fit your schedule, we source a matched equivalent from our other ISO 9001 certified supplier partners rather than leave the position unfilled - genuine when it fits, equivalent when it has to.
Need a Duncan Engineering Ltd spec or quote?
Send the duty, media and sizing you have - we target a quote inside 24 hours.
