Installation and Sourcing Notes
Confirm the outside diameter against the actual cavity or bore dimension. The outside diameter does not directly equal the pipe size.
Check the installation thickness, retention structure, and sealing arrangement before placing an order.
Provide cavity dimensions, target flow and pressure, expected quantity, and destination market for accurate model selection and sample review.
Common Questions
Can I select a model by matching the outside diameter to the pipe size?
No. The outside diameter does not equal the pipe size. Check the actual cavity dimensions, thickness, and retention structure.
What information should I provide for sourcing?
Provide cavity dimensions, target flow and pressure, expected quantity, and destination market. We will review model options and sample requirements.
