Chemtrol 6503 Adapter Coupling
The Chemtrol 6503 is a Schedule 80 polyvinylidene adapter coupling designed for plumbing systems requiring a secure transition between socket and female NPT threads. It suits installers working with 3/4 inch piping who need a durable, chemically resistant fitting for industrial or commercial fluid handling applications.
1360 PSI Pressure Rating and Temperature Range
This coupling handles a maximum operating pressure of 1360 psi at 73 degrees Fahrenheit, with a service temperature range extending up to 280 degrees Fahrenheit. The Schedule 80 construction provides robust wall thickness for high-pressure lines, though pressure capacity decreases as operating temperatures rise toward the upper limit.
3/4 Inch Socket by Female NPT Configuration
The fitting connects a 3/4 inch female socket end to a 3/4 inch female NPT threaded end, and includes a seal for the socket joint. It is not intended for male-threaded connections, solvent welding to non-Schedule 80 pipe, or systems exceeding the stated pressure and temperature boundaries.

Questions about this item
Will the 3/4 in socket end fit my existing Schedule 80 pipe?
Yes, the socket end is made for 3/4 in Schedule 80 pipe so it will match the same diameter you already have.
How can I confirm the 1360 PSI rating is holding after I install it?
Pressurise the line up to the 1360 PSI maximum operating pressure and check the joint for leaks; the included seal is designed to hold at that pressure.
Does the box contain the seal or do I need to buy one separately?
The seal is included with the coupling, so no separate purchase is required.
