Goopy Performance 2mm Apex Seals for RX-7 13b, 13BT & REW

Thanks to our close association with the new UK distributor of Goopy Performance products Essex Rotary can now offer this superb proven more durable alternative to the standard Mazda Apex Seals.

Goopy Apex seals have become renowned for their reliability by withstanding up to 50psi in Drag Racing and still not failing and have even withstood detonation that the Mazda Apex seal could only dream of.

This makes these High Performance Apex seals not only ideal for any N/A, Turbo or Supercharged RX-7 but also ANY standard or tuned REW or 13bt engine .

Also available for the RX-8 engines these seals can be included in your Essex Rotary engine rebuild upon request at a small additional cost.

Sold at a set of 6 complete seals these will easily replace the stock apex seals found in all series 4- series 8 RX-7 engines.

Goopy 2 mm apex seals are .075″ (1.905mm) thick and you should be able to slide a .0015″ feeler gauge into the rotor apex slot with a new apex seal in place.

Goopy Performance 13B 2 mm oversized apex seals measure .078″ +/- .001″ (1.981mm +/- 0.025mm). If your rotor slot measures .077 – .078″, then you may benefit from our oversized 2 mm seals which will allow you to re-gain the .0015 suggested clearance.

If your gap with the seal in place measures .002-.005″ it is still usable, but keep in mind that tighter clearances means greater sealing characteristics.
