Jaltest JTP09 — Round Male Pin Ø4mm (Pair)

The JTP09 is a replacement cylindrical male pin measuring 4mm in diameter, sold as a pair, for use in the Jaltest Multipin Connection system. Alongside its sibling the JTP08 (Ø3.5mm), the JTP09 covers the larger round male pin geometry required to interface with certain vehicle and equipment diagnostic ports that use a 4mm female socket. When your Jaltest multipin connector needs to mate with that port size, the JTP09 is the correct contact.

For shops running Jaltest CV, OHW, AGV, or MHE, the multipin system is the bridge to diagnostic ports that fall outside standard OBD or Deutsch configurations. The JTP09 fills the specific 4mm round male slot in that system — a geometry found on a portion of commercial and off-highway equipment diagnostic connectors.

Part of the Jaltest Multipin Kit System

The JTP09 is one of ten distinct pin types included in the Jaltest Multipin Kit (Part #70002001, MSRP $310.00), which contains pairs of JTP01 through JTP10 plus JDC10AM2 and JDC20AM2 multipin cables. The complete kit ships standard with every Jaltest diagnostics platform (CV #29209, OHW #29211, AGV #29210, MHE #70001049), the Marine hardware kit, and the Data-Link.

Order the JTP09 individually when:

• Your existing Ø4mm male pin is bent, damaged, or missing
• You're building a specific port configuration that requires the 4mm round male geometry
• You want to maintain a full backup pin set for every JTP type to avoid any diagnostic downtime from a single failed component

JTP08 vs. JTP09 — Choosing the Right Round Male Pin

Both JTP08 and JTP09 are cylindrical male pins, differing only in diameter:

• JTP08: Ø3.5mm — for vehicle-side female sockets at 3.5mm diameter
• JTP09: Ø4mm — for vehicle-side female sockets at 4mm diameter

If you're unsure which one you need, measure the female socket on the vehicle's diagnostic port or check the Jaltest cable documentation for the specific vehicle. Calling our tech line at 866-217-0063 is also a fast way to confirm before ordering.

Compatibility

• For use with Jaltest Link V9 multipin connector assemblies
• Compatible with Jaltest CV, OHW, AGV, MHE, and Marine diagnostic platforms
• Works with JDC10AM2 and JDC20AM2 multipin cables
