About Our Products

BESTgasket manufactures HIGH-QUALITY gaskets throughout our entire product line, but here we want to bring special attention to our HEAD GASKETS and REAR MAIN SEALS.

ABOUT OUR HEAD GASKETS

The head gasket is the most critical of all engine gaskets, and therefore demands much of our attention. We make two styles of premium-quality head gaskets:

1) Copper (suffix of “C”) – consists of two outer sheets of a generously thick .010” copper and a low-density graphite “filler” sheet. This high-quality graphite sheet is superior to asbestos, which was used in the old days, and far superior to the non-asbestos materials found in other manufacturers’ modern copper head gaskets. Excellent torque retention is achieved by using superior materials. Also, our graphite filler is impervious to fluids.

Our copper gaskets are definitely “old-school,” but with a modern flair for better performance. They are such works of art, we almost hate to sell them!

Install using using a spray-on sealant like K & W Copper Coat or Permatex Copper Spray-A-Gasket. Always re-torque, no short-cuts.

2)?GraphTite??(suffix of “G”) – MBG is a high performance gasket material combining expanded graphite facings on 0.2mm (0.008″) tang perforated tin-plated steel core. It is ideally suited for internal combustion engine applications such as head gaskets. MBG is compressible and resilient, yet offers excellent bolt torque retention, excellent chemical resistance, and is heat resistant for exhaust gas sealing applications up to 550°C (1000°F) or higher when shielded.

GraphTite??head gaskets have superb sealing characteristics and hold up to the punishment dished out by high-performance engines – high quality all the way. This gasket might be overkill for cruiser engines, but so what . . extra performance never hurts!

Note: For lower volume applications where tooling costs are prohibitive, BESTgasket may also use head gaskets from other manufacturers.

ABOUT OUR REAR MAIN SEALS

Ever since the big gasket manufacturers discontinued using asbestos in the 1990s, rope rear main seals have been a huge problem to the vintage car enthusiast. The non-asbestos rope seals available from the big boys are next to impossible to trim and do a poor job of sealing. BESTgasket has two solutions to this problem.

  • Rubber replacements of rope seals
  • GraphTite? rope seals

BESTgasket has developed rubber replacement seals for the following engines where only rope seals have previously been available:

Buick st-8 40-50 series, 1934-53
Buick V8 364-401-425, 1957-66 *
Cadillac V8 331-365, 1949-58E
Chevrolet V8 265-283, 1955-58
Chrysler V8 392, 1957-58 *
Ford V8 312, 1956-57
Oldsmobile V8 301-324, 1949-56
Oldsmobile V8 371-394, 1957-58

* included in our Engine Rebuilding Sets, others are only sold separately

GraphTite? rope seals are miles ahead of any other rope seal out there.
This marvelous material is easy to trim. . . and it seals!! To ensure exact trimming, each kit includes installation instructions, a special knife, and a few other trimming aids.

Our customers have reported great success with GraphTite? rope seals, finally solving those aggravating rear main seal leaks. No hype here. . . just results.
