O-Rings

O-rings made from standard compounds are available from stock.

Many AS-568A, metric and JIS O-ring sizes in commercial compounds may be available for immediate shipment from your local authorized Kalrez® perfluoroelastomer parts distributor. In addition, DuPont maintains inventories of all AS-568A, metric and JIS
O-ring sizes. Please call your local authorized Kalrez® distributor for current inventory status and estimated shipment dates.

AS-568A


(1)	= The dimensions and tolerances of ring diameters and cross sections of Kalrez® O-rings on this list are as listed. All other quality aspects are in accordance with MIL-STD-413C of 8 Dec 1980, "Visual Inspection Guide for Rubber O-rings," except for white O-rings (compound 1045). O-rings made from compounds other than 4079, 1050, 1045, 1018, and 3018 may not conform to the dimensions shown due to differing shrinkage rates.
(2)	= Width (or Cross Section Diameter)

Metric Standards

Availability

Metric O-ring sizes are normally not inventoried. Orders for quantities, sizes and compounds not in inventory will be placed and committed to within standard manufacturing lead times. Please call your local authorized Kalrez® perfluoroelastomer parts distributor for current inventory status and estimated shipment dates.

Key:


(1)	= The dimensions and tolerances of ring diameters and cross sections of Kalrez® O-rings on this list are as listed. All other quality aspects are in accordance with MIL-STD-413C of 8 Dec 1980, "Visual Inspection Guide for Rubber O-rings," except for white O-rings (compound 1045). O-rings made from compounds other than 4079, 1050, 1045, 1018, and 3018 may not conform to the dimensions shown due to differing shrinkage rates.
(2)	= Width (or Cross Section Diameter)
(y)	= Limited inventory may be available.

Custom O-Rings

Customized cross-section and diameter dimensions are available for shipment in just five working days. We make them to your order using our patented O-ring splicing technology.

Kalrez® QS Spliced O-rings: The Quick-sealing Solution with Long-term Performance

Now, a splicing method created by DuPont enables quick production of O-rings that conform to most industry specifications or to your custom requirements. This exciting technology reduces the manufacturing time for spliced O-rings as well as the cost hurdles associated with custom O-rings. Whether your intended use is prototyping or large-scale commercialization, spliced O-rings deliver a quick-sealing solution with the well known performance of Kalrez® parts.

A Range of Sizes and Compounds to Meet Your Needs

You're no longer bound by industry standard sizes when you need the performance of Kalrez® parts. Kalrez® QS spliced O-rings can be produced in a broad range of customized cross-section and diameter dimensions to meet your specific needs. Cross sections are available within a range of .070" to .500" (1.78 mm to 12.7 mm), with any inside diameter not less than 6.000" (152.40mm). Spliced O-rings are currently available in several compounds, including Kalrez® 4079.

How to Specify Your Part

You can specify Kalrez® QS two ways; industry-standard reference or explicit inside diameter with cross-section dimensions. Kalrez® QS spliced O-rings can be produced according to several industry standards: SAE AS 568, ISO 3601, JIS B2401, or comparable O-ring standard.

Dimensional tolerances for Kalrez® QS are provided in the table below. Surface quality complies with MIL-STD-413C when applying the parting line requirements to the splice area. For other dimensional and surface specifications, contact your authorized Kalrez® distributor.
