What is an X Profile o-ring?
What is an X Profile o-ring?
X-Rings Description X-Rings have a sealing function doubling that of an o-ring, and can be used in numerous static and dynamic sealing applications. Compared to a standard o-ring, the four-lobed X-Ring profile maintains twice the sealing surface.
What is cross section in o-ring?
An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
How do you find the cross section of an o-ring?
Cross Section (CS) = (OD – ID) ÷ 2. If the o-ring is cut, measure the cross section (thickness) of the o-ring and the length. Measure the cross section.
How do you calculate o-ring groove size?
Groove Design: O-Ring Seals
- Calculate the O-Ring groove dimensions. Using the table above, determine the maximum recommended gland depth for your application.
- a. For a rod (shaft) seal:O-Ring Max Groove Diameter = Min Shaft Diameter + (2 x Recommended Gland Depth)
- b.
- c.
What is a quad ring?
Quad-Ring® A variation of the standard O-ring, Trelleborg Quad-Rings® have an X-shaped cross section suitable for sealing a range of static and dynamic applications. This provides higher sealing efficiency and lower friction than conventional O-Rings. Quad-Ring® is a registered trademark of Quadion Corporation.
What size is an L ring?
To discover your ring size, simply measure the inside diameter of an existing fitting ring and check the measurement against our handy chart below….Ring Size Conversion Chart.
| Inside diameter (mm) | Inside circumference (mm) | Ring size |
|---|---|---|
| 16.31 | 51.2 | L |
| 16.71 | 52.5 | M |
| 17.12 | 53.8 | N |
| 17.53 | 55.1 | O |
Is Thicker O ring better?
A thicker seal has more cross-section to withstand the movement and will theoretically handle more cycles than a thinner cross-section. A thicker seal will also have more stability in the groove and be less prone to rolling. However, thick seals will also have more friction in dynamic applications.
Does O ring thickness matter?
For all applications, O-rings with a larger cross- sectional diameter tend to have better resistance to compression set. They also have less volume swell in fluids and are less likely to leak if their surface is scratched.
How do I find the right size O-ring?
O-Ring Size The size of an O-ring can be determined by measuring the diameters and the width of the cross-section. The measurement you will need to include are the internal diameter (ID), outside diameter (OD), and the cross-section width (CS).
How do you read an O-ring size?
Measurement Formulas:
- Outside Diameter (OD) = Inside Diameter + (2 x Cross Section).
- Inside Diameter (ID) = OD – (2 x CS).
- Cross Section (CS) = OD – ID, ÷ 2.
How do you pick O-ring size?
The size of an O-ring can be determined by measuring the diameters and the width of the cross-section. The measurement you will need to include are the internal diameter (ID), outside diameter (OD), and the cross-section width (CS).
How do I know what size O-ring to buy?
Measure the length and the Cross section of the ring. Then divide the length by π (3.142), this will give you the circumference. Take the Cross section from this to give you the Inside diameter.
What is a nominal cross section O-ring?
nominal cross section O-Rings. Until now, O-Ring standards have left a gap between the 1/8” and 3/16” nominal cross sections. In de- signing this new group of O-Rings, we left spacing in the part numbers to allow us to add additional sizes should they be required.
What is the difference between O-rings and 4-lobed and X-ring?
The four-lobed design produces a more secure seal to counteract spiral twisting. This allows the use of a narrower groove width than a standard o-ring groove, but can also be used in a standard o-ring groove. The X-Ring Cross-Section and ID are measured just like o-rings.
How are the O-rings presented in the catalog?
In most cases the O-Rings are presented from top-to-bottom and left-to right. In cases where O- Rings overlap, the label has been positioned so that it will identify only one size. O-Rings that are too large to illustrate are listed in cross sectional groups at that back of the catalog
What sizes does global O-ring and seal offer X-rings?
Global O-Ring and Seal offers X-Rings in standard AS568 sizes, as well as metric sizes. Our part naming convention in the online store is a “Q” preceding the material, durometer, and size. For example, part number QN70230 is an X-Ring made with Nitrile material at 70 durometer in the 230 AS568 size.
