Features
•
Hardened, precision ground parts for durability
•
Low profile adapter for minimal space requirements
•
Fully guided poppet for more consistent reseat
•
Steel adapters are coated with yellow zinc dichromate for
protection from salt spray
•
Polyurethane “D”-Ring eliminates backup rings and
prevents hydrolysis
•
Internal screening protects pilot spring from debris
