Double Studded Adapters

DOYLES stocks a wide variety of Double Studded Adapters (DSA). They enable the user to transition from one size and pressure to another. Most sizes and pressure rating configurations are in-stock for immediate shipment. When the required size and pressure combination is not in stock, it can be manufactured or re-manufactured to fit virtually any combination. All DSA meet API 6A requirements. Typically B7 all-thread studs are installed with grade 2H nuts, but tapped-end and plated studs can be installed when specified at the time of order.
