•
World-wide most commonly used type thread
• Characterized by its major diameter and its pitch
• Designated by the letter M followed by the value of the nominal diameter and the pitch, both expressed in millimetres and separated by the multiplication sign '×' (i.e. M12 x 1.5) |
• NPT Thread = National Pipe Thread
• Taper rate for all NPT threads is 1/16
• The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to straight thread fittings |
 |
 |
• PG Thread = Panzer-Gewinde
(also Panzer-Rohr-Gewinde)
• German thread type
• Depth of thread smaller than NPT or Metric, but larger flank angle |
• BSPP Thread = British Standard Pipe Parallel Thread
• Parallel (straight) thread with a constant diameter, denoted by the letter G
• Symmetrical V-thread in which the angle between the flanks is 55°
(measured in an axial plane)
• One-sixth of this sharp V is truncated at the top and the bottom
• Threads are rounded equally at crests and roots by circular arcs ending
tangentially with the flanks
• The theoretical depth of the thread is therefore 0.64 times the nominal pitch |

| Note: Torque
for dome nuts was determined using a metal rod.
It may vary for cable, depending on the crush
resistance of the cable. We recommend to determine
the actual torque empirically, testing the actual
cable used. The values shown above are for reference
only. |
| Note: Nylon
strain relief fittings installed in a threaded
connection and exposed to elevated temperature
should be retained with a sealant such as Locktite® to
avoid a loose connection when temperature fluctuates. |
Custom Drilling Solutions!
- Any special insert hole or profile configuration is available for a minimum order of 1,000 pieces.
- No Charge Manufacturing Fee - In 12-14 weeks or a one time Expedite Fee reducing manufacturing to 6-8 weeks.
For small quantities we suggest drilling or machining the inserts yourself
Drilling/Machining guidelines:
- We suggest drilling the frozen solid insert.
- Drill holes by using a standard high-speed steel drill bit of the proper size at approx. 2500 RPM.
- Drill holes with insert installed in Strain Relief Fitting as a fixture.
- Keep a minimum distance of 1 mm (.04 in) between holes.
- The outside holes can be located right against the lip of the strain relief body, as sufficient insert material remains between the hole and the body wall
due to the design of the cord grip.
Important:
Design Parameters: Cable diameter should not be less than 80% of hole diameter and the difference between hole and cable diameter should never exceed
.04" (1 mm). The Multi Cable fittings will meet NEMA 4x = IP65 if the design parameters are complied with.
To verify a submersible NEMA 6= IP68 application, the final assembly of cables and fittings must be tested by the customer or submitted at the customer's
expense to an independent test lab. |
