Concrete: Pad Caps and Retainer Rings - Steel

Our pad-cap retainer rings hold neoprene pads that fit into the ends of concrete test cylinders. Made from plated high-alloy steel to resist rust and deformation fatigue. Bearing surfaces machine-planed to within 0.002". Supplied two per set.

These neoprene pad inserts are made from a tough elastomeric material that evens out and fills irregularities in the ends of concrete cylinders to assure even distribution of test loads for consistent results.

Requirements for use of neoprene pads:

Compressive Strength, psi

1,500 to 6,000, 50 durometer
2,500 to 7,000, 60 durometer

7,000 to 12,000, 70 durometer with qualification testing
