Wiper Arm Types: Complete Guide

Identify your wiper arm connector type to find the right replacement blades. There are six common types used across modern vehicles.

J-Hook

The most common wiper arm connector, found on the majority of pre-2018 vehicles. Features a curved, hook-shaped end that the wiper blade slides onto. Easy to find universal replacement blades.

Common Vehicles
Most pre-2018 vehicles from Toyota, Honda, Ford, Chevrolet, and more
How to Identify
Look for a curved, J-shaped metal hook at the end of the wiper arm

PTB (Push Tab Button)

A modern connector increasingly common on 2018+ vehicles. Uses a small plastic tab that you press to release the blade. Provides a more secure, low-profile attachment than J-Hook.

Common Vehicles
2018+ Toyota, Honda, Hyundai, Kia, Subaru, and many other newer models
How to Identify
Look for a small plastic button or tab where the blade meets the arm

Pin

Uses a small metal pin to secure the blade to the arm. Common on European vehicles, particularly Audi, BMW, and Volkswagen. Requires pin-compatible replacement blades.

Common Vehicles
European vehicles — Audi, BMW, Volkswagen, Mercedes-Benz
How to Identify
Look for a small metal pin (about 3-4mm) connecting blade to arm

Bayonet

A slide-on connector where the blade slides onto a flat arm end and locks into place. Found on select GM vehicles and some European models. Distinct from J-Hook by its flat profile.

Common Vehicles
Select GM vehicles (Chevrolet, GMC, Buick) and some European models
How to Identify
Look for a flat, rectangular arm end that the blade slides onto

Side Lock

Features a side-clip mechanism that snaps the blade onto the arm from the side. Used on select vehicles from multiple manufacturers. Look for a release tab on the side of the connector.

Common Vehicles
Select models from Volkswagen, Volvo, Renault, and others
How to Identify
Look for a clip or latch on the side of the blade connector

Narrow

A slim pin variant designed for newer compact vehicles. Similar to the standard pin type but with a narrower profile. Requires narrow-specific replacement blades.

Common Vehicles
Newer compact vehicles from various manufacturers
How to Identify
Similar to pin but noticeably slimmer — compare width to standard pin
