  • Quick-connect design speeds transmission line repairs
  • Plastic body withstands -65 °F to 350 °F operating range
  • 250 psi rating handles high-pressure cooler circuits

Quick connector for transmission lines

The SUR&R TR720 quick connector joins 3/8 inch transmission oil cooler rubber lines using a female-to-male universal fit. It is designed for automotive repair shops and DIY technicians who service cooling circuits on cars and light trucks. The plastic body withstands a temperature range from minus 65 to 350 degrees Fahrenheit. Each pack contains two connectors for a complete line repair.

Rated for 250 psi working pressure

The fitting handles up to 250 psi, covering normal transmission cooler pressures with headroom for pressure spikes during cold starts. It is not suited for high-pressure hydraulic systems that exceed this rating. The universal design matches the referenced 52HJ26 rubber hose specification. Installers should verify line compatibility before assembly.

Female-to-male universal connection

The single specification that decides fit is the female-by-male universal quick-connect interface for 3/8 inch pipe size. If the existing line uses a different gender, diameter or locking style, this connector will not seal. No adapters are included in the two-piece package.

Questions about this item

Will the TR720 3/8" connector mate with the 52HJ26 transmission oil cooler rubber lines I already have?

Yes, the TR720 is listed for use with 52HJ26 transmission oil cooler rubber lines, so it will connect directly to that existing hose.

How can I confirm the TR720 quick connector is seated and sealing correctly once installed?

Push the connector until it clicks, then pull firmly to verify the lock engages; with the system pressurised up to 250 psi, no fluid should escape at the joint.

The pack contains two connectors — are any retaining clips or special tools included, or must I source them separately?

The package supplies only the two plastic quick connectors; any retaining clips or disconnect tools required for your specific line are not included and must be obtained separately.
