MCB 570/900/1000 PREMIUM VITON VALVE SEAL SET (8pcs)

One complete set of MCB Premium Viton Valve seals. These are correct for most all Polaris 570/900/1000 Prostar engines EXCEPT the early 900's that used a separate spring seat from the seal. If your machine uses Polaris part # 3610212 this is the correct and upgraded seals.

Viton seals have several very crucial differences that make them especially well suited to Powersports applications. While both Viton and other seals both serve as great sealing options at moderate temperatures, Viton is far superior to other seals for high temperature applications. Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more a limited time. Valve seals made of non-Viton materials, such as Poly, are only effective up to 250°F and although have good overall life not the best application for Powersports use.

These are brand new production seals. Viton has good flexibility like Nitrile, which means it can handle some runout between the valve stem and guide. It is also considered to be a more durable material than silicone. Viton also has better wear resistance than most other seal materials, making it a good choice for applications where long term durability is a must.

Viton seals provide less friction as well, due to 5% Teflon.

Fits Polaris Ranger, General, RZR, Turbo, XP, ACE 900 & 1000 "2013 and UP"
