60 Durometer Commercial Nitrile Sheet
60 Durometer Commercial Nitrile Sheet is a commercial grade Nitrile (NBR) blend rubber sheet with a durometer of 60 ±5 Shore A, a minimum tensile strength of 800 psi, and a minimum elongation of 350%. The material carries a compression set of 60% maximum at 22 hours/100°C and a service temperature range of -30°F to +190°F (-34°C to +88°C). The sheet is specified to ASTM D2240 Z1=Hardness 60 ±5 Shore A and is supplied in a smooth black powdered finish in 36″ and 48″ widths up to 1/2″ thickness. Available – cloth-inserted (CI) construction for enhanced dimensional stability.

Compliance
- ASTM D2240 Z1=Hardness 60 ±5 Shore A — Compliant
- Commercial and light industrial gaskets and seals in oil-exposed equipment
- General-purpose oil-resistant gasketing where a medium-firm 60 Shore A hardness is required
- Machine and equipment sealing in moderate oil-contact service environments
- Die-cut commercial-grade NBR components for general industrial fabrication
- Sheet stock for cutting and converting in moderate oil-contact sealing applications
Common industries: Industrial manufacturing, commercial equipment, machinery and equipment, maintenance and repair operations.
60 Durometer Commercial Nitrile Sheet is a medium-firm NBR blend rubber sheet engineered for commercial and light industrial oil-resistant gasketing where a 60 Shore A hardness is specified and cost-effective performance is the primary requirement.
The commercial grade designation reflects a formulation optimized for broad applicability across general sealing, machine gasketing, and fabrication use rather than the tighter mechanical thresholds of the premium grade.
With a minimum tensile strength of 800 psi, minimum elongation of 350%, and compression set of 60% maximum at 22 hours/100°C, 60 Durometer Commercial Nitrile Sheet provides adequate mechanical properties for general-purpose applications where the premium grade’s performance envelope is not required. The sheet is available in 36″ and 48″ widths from 1/16″ to 1/2″ thickness in a smooth black powdered finish.
The material is specified to ASTM D2240 Z1=Hardness 60 ±5 Shore A, establishing the hardness tolerance as the primary specification parameter. Oil resistance in ASTM Oil #3 at 70 hours/100°C is 120% maximum volume change per ASTM D471, indicating acceptable dimensional stability under petroleum oil exposure appropriate for commercial sealing service. No heat aging data is listed on the manufacturer’s TDS for this grade.
Compliant with ASTM D2240 Z1=Hardness 60 ±5 Shore A.
What differentiates 60 Durometer Commercial Nitrile Sheet from the premium grade at the same durometer?
60 Durometer Commercial Nitrile Sheet is a commercial grade NBR blend optimized for broad general-purpose applicability, with minimum tensile of 800 psi and compression set of 60% maximum. A premium grade at equivalent durometer would carry higher tensile strength, a tighter compression set limit, and typically a broader fluid resistance dataset including heat aging data and multi-fluid ASTM D471 test results. For applications with documented mechanical performance thresholds or stringent fluid exposure requirements, the premium grade is appropriate; for general commercial sealing where hardness conformance is the primary specification, 60 Durometer Commercial Nitrile Sheet provides a cost-effective solution.
Why does compression set matter for commercial nitrile gasketing?
Compression set determines how well a rubber gasket maintains residual sealing force after sustained compression in a bolted joint. A gasket with high compression set permanently deforms and loses the elastic recovery that keeps the joint sealed over time. At 60% maximum (22 hrs @ 100°C), 60 Durometer Commercial Nitrile Sheet is specified for general commercial sealing service — applications where moderate long-term sealing force retention is acceptable and where joint designs can accommodate the expected relaxation over service life.
What is the service temperature range for 60 Durometer Commercial Nitrile Sheet?
-30°F to +190°F (-34°C to +88°C), as listed on the TDS (general guideline).
Is 60 Durometer Commercial Nitrile Sheet suitable for oil-exposed applications?
Yes, for moderate oil exposure. Oil resistance in ASTM Oil #3 at 70 hours/100°C shows a maximum volume change of 120% per ASTM D471. This indicates controlled dimensional change under petroleum oil immersion at elevated temperature, appropriate for commercial sealing applications involving incidental or sustained contact with petroleum-based industrial oils.
How should 60 Durometer Commercial Nitrile Sheet be specified?
Specify 60 Durometer Commercial Nitrile Sheet, thickness (1/16" through 1/2"), width (36" or 48"), compliance requirement (ASTM D2240 Z1=Hardness 60 ±5 Shore A), dimensional tolerances, and finished format.
