A flanged joint is only as good as the gasket in it. Champion Big-Lock flange gaskets are the sealing element between a Big-Lock stainless flange and whatever it bolts to: a dryer, a receiver, a filter housing, a compressor discharge. Sizes 73mm through 220mm, in standard and high temperature.

Standard or High Temperature
The standard gasket covers the ordinary case: air downstream of an aftercooler or a dryer, at normal shop temperature. The high temperature gasket is for the places where the air has not been cooled yet.
The one that catches people out is compressor discharge before the aftercooler. Air leaving a rotary screw airend can be well over 180 F, and on a reciprocating machine higher still. If the flange is between the compressor and the aftercooler, it wants the high temperature gasket. Downstream of the cooler, standard is correct and considerably cheaper.
If you are not sure where the flange sits in the sequence, send us the layout. Getting this wrong does not fail immediately, which is the problem: a standard gasket on a hot line hardens, takes a set, and starts weeping months later.
Keep Spares, Because You Will Reopen the Joint
Every time a flanged joint comes apart for service the gasket should be replaced. It has been compressed, it has taken the shape of the flange face, and it will not seal the same way twice. At $17 to $83 at list for a standard gasket this is the cheapest insurance in the system.
The sensible stocking policy on a plant with Big-Lock flanges is one spare gasket per flange size in use, kept with the maintenance spares rather than ordered when a joint is already open and the line is down.

Specification note. Champion's August 2026 price list publishes description, part number and list price for the Big-Lock range and nothing else: no material, no temperature band in degrees, no pressure rating, no weights and no dimensions. We have not found a Big-Lock gasket datasheet. Rather than publish figures from another manufacturer's grooved range and present them as Champion's, this listing states only what Champion publishes. If you need the actual temperature limit in writing before you order, ask us and we will get it from the factory.
Ideal Applications
Flanged connections to refrigerated and desiccant dryers, receiver tank inlet and outlet flanges, filter and separator housings, compressor discharge, heat exchangers, and anywhere a Big-Lock aluminum main meets flanged equipment.
Building a Complete Big-Lock System
- Big-Lock aluminum pipe, 73mm to 273mm
- Stainless flange kits, standard and high temperature, which include a gasket
- Flange bolt and gasket kits
- Straight union couplings
- Replacement coupling seals
- Air dryers, the most common thing on the other side of the flange
Ordering Notes
- All Big-Lock products and accessories are NO CANCEL / NO RETURN, per Champion's current price list.
- Freight: freight collect from Huntersville, NC 28078 or Las Vegas, NV 89113.
- Shipping weights: Champion publishes no weight for any Big-Lock fitting, so no catalog weight is carried on these variants.
- Photography: Champion publishes no photograph of the Big-Lock flange gaskets, so this listing is deliberately shown without an image rather than with a stand-in from another manufacturer's grooved range.
NOTE: Actual product may be different from pictured!
