The Gast SSP-87R6-01 Non-biased Valve Kit at Kinequip is a silencer upgrade kit designed for all Gast 87R twin cylinder rocking piston models used for pressure without a biased relief valve. This kit improves airflow and reduces noise, helping your compressor or pump maintain peak performance. It includes attenuation chambers with internal silencers, a valve plate with custom O-rings, circular O-rings, and port plugs. For units with more than 1000 hours or 1 year of use, pairing this kit with a Gast preventative maintenance kit is recommended.
To determine if your 87R model uses a biased relief valve, check the part number: if it includes an “R” (e.g., 87R642-101R-N470X), it does, and you need to order SSP-87R6-02. Still unsure? Contact us, and our knowledgeable representatives can help.
