MEASURE · SELECT · INSTALL

Match the RST stem, flange and underside profile

RST is a T-shaped series: the flange rests on the face while the stem enters the bore. Read the E value for the selected model as well as A–D.

01 / MEASURE

Separate the outside fit from the underside recess

Use these definitions with this page’s drawing and model table. Dimensions are in mm; letters may describe different features in other series.

AStem outside diameter
Across the straight stem, above the tip chamfer. Compare with the finished hole diameter and tolerance.
BFlange outside diameter
Across the head. Check the flat seating area and neighboring parts.
CStem length
From the flange underside to the tip. Check blind-hole depth or clearance behind a through-hole.
DFlange thickness
The head height above the seating face. Overall part height in the drawing is C + D.
EUnderside recess diameter
The original section shows a recess from below, with the head closed above it. Rows include E = 0 and nonzero values; confirm the selected model, recess depth and remaining head thickness on its drawing.
  1. Measure the rigid opening. Record the bore diameter in two directions, its tolerance, chamfer and available depth. A is a part dimension, not an automatic hole specification.
  2. Check space on both sides. Allow room for B and D above the face and C below it. Identify any feature that could enter or contact the underside recess.
  3. Compare complete rows. Do not select by A alone or assume that models with matching A and B have the same underside profile. The E dimension is not a wire or tube through-hole specification.

02 / SELECT

Choose the seating and retention you need

A flange resting on a flat face

Use the head as the seating reference and specify access for removal. Verify stem fit and insertion force on the actual bore.

A panel that needs a retaining lip

The RST profile has no rear retaining lip. If mechanical capture behind a panel is required, compare RSB and provide the panel thickness.

03 / INSTALL

Seat the flange without folding the stem

RST T-shaped stopper section in a through-hole, with the flange on the surface and a blind underside recess
A recessed RST variant is illustrated. The head remains closed; use the E value and approved section for the actual model. Blue = rubber part; gray = mating component. Schematic, not to scale.

Trial assembly checks

  1. Prepare and align. Inspect the bore edge, remove debris and center the stem. Press evenly on the head without driving a tool into the underside recess.
  2. Check the head and stem. Confirm the flange sits evenly, the stem has not folded and the tip clears any rear obstruction.
  3. Trial fitting and removal. Record insertion and pull-out behavior against the assembly requirements. Do not rely on the flange to provide an undercut lock.
  4. Confirm the closing duty. Where sealing is required, validate the chosen model and compound with the actual medium, temperature and pressure or vacuum.

Send for a fit review: RST part number and E value, hole diameter and tolerance, available depth, flange space, removal frequency, material and service conditions. Add these details to your inquiry.
