ABA Nova New housing design for a high clamping force.
ABA Nova S20, Stainless S40(W4) and Acid Resistant S50(W5)
The highly versatile ABA Nova clamp is an ideal choice for smaller dimensions of hoses. The base of the housing is cut back and the internal tolerances are very close: a few hundreds of a millimetre. Available for a wide range of hose dimensions, it retains its roundness and sealing qualities even on the smallest of hoses.

ABA Nova Standard-S20(W1): Screw: Electro zinc plated. Band: 8-12 to 40 mm Galfan. Housing: Painted.

ABA Nova Standard-S20(W1): Screw: Electro zinc plated. Band: 32-44 to 85 mm Aluzink. Housing: Painted.

ABA Nova Stainless-S40(W4): All parts are made of SS 2333/AISI 304 stainless steel.

ABA Nova Acid Resistant-S50(W5): All parts are made of SS 2343/AISI 316 stainless steel.
