Zoro Select Buna-N O-Ring 214 Pack
These internally lubricated Buna-N O-rings suit maintenance teams and DIY mechanics who need reliable static seals for hydraulic or pneumatic systems. The pack contains 25 black rings sized to Dash 214 dimensions for standard groove compatibility.
Round Cross-Section with Medium-Hard Durometer
Each ring measures .9 in actual inside diameter and .139 in actual width, giving a 1.262 in outside diameter that seats cleanly in inch-standard grooves. The 70A durometer resists extrusion while the internal lubricant eases installation and reduces assembly damage.
Check Groove Dimensions and Temperature Limits
Verify your groove matches the Dash 214 nominal 1 in inside diameter and 1/8 in width before ordering. The material operates from -30 to 250 degrees F and is FDA approved, but it is not X-ray detectable for food-line inspection requirements.

Questions about this item
What dash number and actual inside diameter does this Buna-N O-ring have?
It is a Dash 214 ring with an actual inside diameter of 0.9 in and an actual width of 0.139 in.
What groove dimensions are needed to fit the actual outside diameter of 1.262 in?
The groove must accommodate a 1.262 in outside diameter with a 0.139 in cross-section width for proper seating.
How should the internally lubricated surface be handled during installation to avoid damage?
Install dry without added grease; the internal lubrication migrates to the surface, and extra lubricant can cause the ring to slip or extrude.
