Description
Product Overview
The H-Jun Transmission Cooler Line Connector is engineered for precision and durability. Crafted from solid brass, each fitting resists corrosion, wear, and deformation, ensuring a stable connection for the transmission oil cooler line. The metric parallel thread (M12x1.5) matches OEM specifications, providing a seamless, leak‑free seal. Packaged as a 2‑pack, the connectors measure 1 x 1 x 0.1 inches and weigh just 0.03 kg each, making them lightweight yet robust. Designed specifically for the Toyota Corolla 1.8L (1998‑2002), they serve as a direct replacement for factory‑issued parts, eliminating the need for modifications.

Usage
These connectors are intended for installation in the transmission cooling circuit of compatible Corolla models. Ideal for both professional mechanics and DIY enthusiasts, they simplify the replacement of worn or damaged lines. Install the connector on the cooler inlet or outlet, secure with the appropriate hose clamp, and verify torque according to the vehicle’s service manual. The brass construction tolerates high temperatures and fluid pressures, making it suitable for daily driving, performance tuning, and heavy‑load conditions.

FAQ
Will these connectors fit other Toyota models?
The connectors are dimensionally matched to the 1998‑2002 Corolla 1.8L transmission cooler line. While they may physically thread onto similar sized lines, we recommend confirming thread size and fitment for other models before purchase.
Can I use these connectors with a different coolant line material?
Yes, the brass fittings are compatible with standard rubber or silicone transmission cooler hoses. Ensure the hose clamp is properly tightened to maintain a secure seal.
What torque specification should I use when installing?
Follow the vehicle’s service manual, typically 8‑10 Nm for the connector thread. Over‑tightening can damage the brass threads, while under‑tightening may cause leaks.
Are these connectors covered by a warranty?
H-Jun offers a one‑year limited warranty against manufacturing defects. Contact our support team with your order details for assistance.
How do I know if my transmission cooler line needs replacement?
Signs include coolant leaks, reduced transmission temperature regulation, or visible corrosion on existing fittings. Replacing the line connectors can often resolve these issues without a full line overhaul.
