PEERCHEER offers BTW NTW HTW thin wall adapter couplings for use with BTW NTW HTW thin wall core barrels. BTW NTW HTW adapter mates between the locking coupling and core barrel outer-tube, providing the pocket into which the head assembly latches deploy. Q series adapter couplings are available for application in standard DCDMA B N H size.
PEERCHEER’S adapter couplings are made of a high quality alloy steel for increased durability.
