Hose lock Ring

RB12/02A - Hose Coupling Cover (post-2009)Used in conjunction with 2 x RBCT1 cable ties[N.B. Pre-2009 models were fitted with the RB12/01 and RB12/02 Hose Clamps, Inner & Outer]NOTE: If you are replacing pre-2009 T-piece connections (Inhale and Exhale) with the RB12/02A, then you must also replace the Inhale and Exhale locking rings with the 2009 modified locking rings RB12/03IN and RB12/03, as these two fittings have a different internal diameter to the old rings.
