A sanitary clamp connection brings matching ferrule faces and a gasket together with a surrounding clamp. Product ratings depend on the exact clamp, ferrules, gasket, size, temperature and installation.

Enter an illustrative angle, travel endpoints and percentage endpoints. Outputs are range arithmetic and a geometric projection only, not real clamp travel, gasket compression, force, sealing or pressure capacity.
Equation Used
- Entered travel and percentage endpoints are sorted before reporting.
- Projection treats entered travel as one leg of an ideal right triangle at the entered angle.
- The schematic lever phase is illustrative and is not linked dimensionally to the entered travel.
- No clamp, ferrule or gasket dimensions are represented.
- Force, torque, pressure, temperature, material behavior, deformation, leakage, shock, fatigue, hygiene and safe selection are omitted.
Clamp, Ferrules and Gasket
Rubber Fab's gasket instructions show a sanitary connection assembled by centering the gasket, mating the flange faces, fitting the clamp groove and tightening the clamp correctly. Dixon describes its Clever Clamp as a sanitary-connection clamp with a self-locking lever and controlled gasket compression.
The drawing keeps those broad components. It does not reproduce a product's internal linkage or dimensions.
What This Calculator Does
The tool sorts two entered travel endpoints, reports their midpoint, and applies x=s tan(alpha) as an ideal right-triangle projection at each endpoint. It separately sorts two entered percentage endpoints and reports their midpoint.
None of those inputs is measured or predicted by the calculator. They are illustrative values for exploring arithmetic.
Illustrative Range Arithmetic
shi = max(s1,s2)
smid = (slo+shi)/2
x = s tan(alpha)
cmid = (min(c1,c2)+max(c1,c2))/2
The projection is not a clamp constitutive law or linkage solution.
Worked Arithmetic Example
For travel endpoints 3 and 6 mm, the sorted midpoint is 4.5 mm. At an illustrative 20 degree angle, the ideal projections are about 1.09 and 2.18 mm. Percentage endpoints 15% and 25% have a midpoint of 20.0%.
These numbers do not establish gasket squeeze, clamp force or sealing performance.
Model Boundary
- Mechanical arrangement: matched sanitary ferrules, centered gasket, surrounding clamp and a documented self-locking lever product.
- Calculated: sorting, midpoint arithmetic and an ideal tangent projection.
- Not calculated: actual over-centre position, lever travel, clamp-band profile, ferrule motion, gasket compression, clamp force, hand force, torque, contact stress, pressure rating, temperature effects, shock/water hammer, leakage, fatigue, cleanability or safe product selection.
Frequently Asked Questions
Does the calculator predict real gasket compression?
No. The percentage endpoints are user-entered labels.
Is x=s tan(alpha) a clamp design equation?
No. It is an ideal right-triangle projection only.
Does the animation show a specific self-locking linkage?
No.
Can the results determine pressure rating?
No.
Do the results apply to every gasket material?
No.
Can this approve a sanitary or pressure connection?
No. Use the exact component manufacturer's current instructions and ratings.
