Set of 4 standard replacement piston body seals for regulators.
The original Scubatec NBR O-ring Kit, available on DIR-STORE, contains 4 large seals with a 2100 size specification. This O-ring is an internal structural component, designed to ensure the main watertight seal on the larger diameter of the piston in balanced or unbalanced piston first stages.
Key Features and Benefits:
-
Dynamic NBR Compound: High-resistance nitrile rubber formulation, optimized to reduce sliding friction along the wall of the pressure chamber during inhalation cycles.
-
Specific Size 2100: Calibrated dimensions and geometric tolerances to fit perfectly into the large piston groove, preventing twists, micro-leaks, and intermediate pressure variations.
-
4-Piece Maintenance Kit: The ideal stock for repair technicians, dive centers, or experienced divers who perform their own annual air regulator overhauls.
