4in Unbonded Capping Neoprene Pad Cap, 70 Durometer (12 Pack)
Sold individually. Two are required for compression testing of concrete cylinders. Choose 4in Unbonded Capping Neoprene Pad Cap, 70 Durometer to order one pad cap.
4in (101.6mm) Neoprene Pads are available in 50, 60, or 70 durometer for compressive strength testing of 4x8in concrete cylinders, and meet requirements of ASTM C1231/1231M and AASHTO T 22. These 0.5in (12.7mm) thick pads flow during compression to fill irregularities in cylinder ends and assure uniform load distribution. The 4in Steel Retainer Set is sold separately and is required to contain the pads at each end of the concrete cylinder. Two pads are required for testing. Pads are reusable in up to 100 tests, and are sold individually or in a package of 12.
The 4in, 70 Durometer Pads are suitable for testing concrete strengths from 4,000-7,000psi (28-50mPa). With further qualification testing by user, 70 durometer pads can be used to test concrete with strengths from 7,000-12,000psi (50-80mPa).
Neoprene Compression Pads Strength
Compression pads are available in several hardnesses:
- 50 duro for design strength 1500 to 6000 psi
- 60 duro for design strength 2500 to 7000 psi
- 70 duro for design strength 4000 to 12000 psi
- 90 duro is designed for high strength compression
The Neoprene Caps are sold individually and two are required for compression testing of concrete cylinders.
Per ASTM C1231, the neoprene pad can be reused up to a maximum of 100 times.
Neoprene Pad Caps Meets Test Methods:
- AASHTO T22
- ASTM C 1231

The 4in Unbonded Capping Neoprene Pad Cap is an essential tool for compression testing of concrete cylinders. This product is sold individually, but two are required for testing purposes. Each pad cap is made of durable neoprene material and has a durometer rating of 70.
These 4in Neoprene Pads are designed to meet the requirements of ASTM C1231/1231M and AASHTO T 22. They are available in three different durometers - 50, 60, and 70 - to accommodate different levels of compressive strength. The 70 durometer pads are specifically suitable for testing concrete strengths ranging from 4,000 to 7,000 psi. With additional qualification testing, they can also be used for concrete strengths up to 12,000 psi.
The 0.5in thick neoprene pads are known for their ability to flow during compression, allowing them to fill irregularities in the cylinder ends and ensure uniform load distribution. To contain the pads at each end of the concrete cylinder, the 4in Steel Retainer Set is required and sold separately. Each testing procedure requires two neoprene pads.
Not only are these neoprene pads durable and reliable, but they are also reusable. In fact, they can be reused in up to 100 tests, making them a cost-effective option for concrete testing. Each pad cap can be purchased individually, or as a package of 12.
In terms of hardness, the 4in Unbonded Capping Neoprene Pad Cap is classified as a 70 durometer, which is designed for concrete strengths ranging from 4,000 to 12,000 psi. There are also other options available, including 50, 60, and 90 duro pads, each suitable for different design strengths.
This product meets the test methods specified by AASHTO T22 and ASTM C 1231, ensuring its compliance with industry standards. To fully equip yourself for concrete testing, check out our full line of Concrete Capping and Unbonded Cylinder Capping products.
