We provide a complete line of replacement poppets and springs for ICHI, Ball, Gas & Air Specialties, Clark and Cooper poppet valves. Both our fully-machined and injected-molded poppets are made out of virgin nylon, super-tough Zytel or PEEK. Send us an E-mail and let us know what your current specifications are and we can send you a sample part. For more information on how we can reduce your cost, look at ICHI's specially-engineered poppet valve or have your old valves rebuilt at our valve repair shop.
