What is the difference between MALE and FEMALE ends?
Example: A 6 inch male end will fit into a 6 inch female pipe. The Male ends of reducers/increasers are crimped.

Note: Gas venting systems must have all male connections pointing up. Solid fuel systems must have all male connections pointing down. Call 1-866-941-5112 for help.

Our reducers/increasers come with 2 female ends. We can custom crimp what you need for your order or you can do it yourself with a crimping tool.
