Adaptability

Introduction

Parker introduced Japanese Industrial Standard (JIS) adapters

in the early 1990s to address market requirements for OEM and

replacement fittings. These fittings are typically used as hose

adapters on equipment designed and/or manufactured in Japan

andKorea.Parker’s JISadapters are designedwith 30° flare and

60° cone connections and typically incorporate BSP threads.

Parker JIS adapters are designed with BSPP and BSPT port

ends and two styles of hose ends: T4 (30° flare, BSPP threads)

and P4 (60° cone, BSPP threads).Two additional Parker series

of fittings, KA (Komatsu flare) and K4 (BS B5200) adapters,

are similar to JIS style fittings and appear i

The T4 and P4 interfaces provide end user flexibility of con-

necting to the most common Parker hose ends available as

listed in Table

Parker’s JISadapter offering that uses theBSPPport connection

are manufactured in accordance with the JIS B2351 type “O”

port connection which is commonly used for higher pressure

systems. Fig.

It should be noted that Parker offers two very similar cone style

BSPP adapters — P4 and K4. Parker’s K4 (60 cone, BSPP) fit-

tings conform toBS5200, whileParker’s JIS cone adaptersmeet

JIS B8363 specifications.

These fittings, while very similar,

are not interchangeable.

See the

K4 section

of this catalog

for more specific information on interchangeability.
