Legris

Legris 3666 08 10 8mm x 10mm Push-to-Connect Nickel Brass Coupling

SKU CH-CQJ7-SXAZH

Connects 8 mm and 10 mm tubes with push-to-connect nickel-plated brass rated to 435 psi and 302 °F

  • Push-to-connect design speeds installation with no tools required
  • Nickel-plated brass construction resists corrosion for long service life
  • Connects 8 mm tube to 10 mm stem for flexible routing
  • Rated to 435 psi for demanding fluid systems
  • Operates from -4 °F to 302 °F across wide temperature range

8mm x 10mm Push-to-Connect Adapter

This nickel-plated brass adapter joins an 8 mm tube to a 10 mm stem using push-to-connect ends on both sides. It suits pneumatic or fluid circuits that need a quick, tool-free joint between those two diameters. The fitting is rated for 435 psi and a temperature range of -4 to 302 degrees F.

Replacing Threaded Reducers

It replaces threaded reducers or compression fittings where faster assembly and disassembly are valued. The jump is worth it when maintenance cycles are frequent or when vibration makes threaded joints prone to loosening. Push-to-connect action cuts installation time without sacrificing the pressure rating.

Pressure and Temperature Limits

The 435 psi maximum pressure and 302 degrees F upper temperature define the safe operating envelope for the nickel-plated brass body. Exceeding either limit risks seal failure or fitting deformation. California Proposition 65 notices also apply because the product contains listed chemicals.

Questions about this item

What tube size does the 8mm end of the Legris 3666 08 10 coupling accept?

The 8mm end accepts a 5/16 inch tube, which corresponds to the 8mm designation in the model number.

How do I install this push-to-connect fitting without damaging the nickel-plated brass body?

Push the tube firmly into the fitting until it seats against the internal stop; do not use a wrench on the body, only on the hex if present, to avoid marring the nickel plating.

When should I replace this coupling given its 435 psi pressure rating and 302°F temperature limit?

Replace the fitting if you see cracks, deformation, or corrosion on the nickel-plated brass, or if the system pressure or temperature will exceed the 435 psi and 302°F ratings.
