Series 707 TLX - 1”

TLX is a Flat-Face twist lock coupling for the toughest applications in the construction and demolition segment. This super-duty quick connect coupling is designed to work with the highest surge flows and the toughest pressure impulses. TLX is made from high alloy steels with Zinc-Nickel surface treatment for a long life in the harshest conditions. The Series is available in sizes from ½” to 1 ½” to cover most applications.


The couplings and nipples are also available in 4 other sizes: ½” (Series 507), ¾” (Series 607), 1 ¼” (Series 807) and 1 ½” (Series 907) http://www.cejn.com/upload/download/Brochures/tlx-twist-lock-series/TLX-en.pdf (TLX product folder PDF)

Technical data
Flow rate: 291 l/min (64.0 GPM) @ 3bar ΔP **
Temperature range: -30°C — +100°C (-22°F — +212°F)
Material coupling: High alloy steels with Zinc-Nickel surface
Material nipple: High alloy steels with Zinc-Nickel surface
Material seal: Nitrile (NBR)
Max. working pressure connected: 420 bar (6091 PSI)
Max. working pressure disconnected: 400 bar (5801 PSI)
Min. burst pressure connected: 1680 bar (24366 PSI)
Min. burst pressure disconnected: 1000 bar (14503 PSI)
Connectability: Connection with residual pressure only limited by operator strength
Disconnection under pressure: Disconnection with residual pressure in the system is allowed

(**) - If the application is constantly above this flow rate on respective coupling size, a larger coupling size should be considered to avoid too high pressure drop. The couplings can handle much higher flow rate during short time periods, but there is a risk of heat build-up in the system. Surge flows far above normal flow rate is in general not a problem.

- TLX is pressure impulse tested at 7614 PSI (525 bar) for 1.000.000 impulses acc. to ISO 7241-2. (Flow Rate) - If the application is constantly above this flow rate on respective coupling size, a larger coupling size should be considered to avoid too high pressure drop.
