Description

HPA SERIES

HIGH PRESSURE,

BALL SEAL,

SCREWED COUPLINGS

INTRODUCTION

Holmbury High Pressure Ball Seal Screwed Couplings

can be connected and disconnected even with a low

residual hydraulic pressure in the line. The screw

connection mechanism eliminates Brinelling

(indentation of the locking balls into the retaining

groove) and thus makes the couplings suitable for high

pressures and pressure pulse applications. Two sizes

are offered, 1/4" and 3/8" NPT.

FEATURES

 Compatible with all high pressure pump and cylinder

manufacturers (Enerpac, SPX, Larzep and Hi-force)

 Connection and disconnection can be performed

even with low residual hydraulic pressure in the line.

 Screw thread retaining mechanism eliminates

Brinelling

APPLICATIONS

General industrial equipment

MATERIALS

Zinc plated carbon steel body material with nitrile seals

and PTFE backing ring. Other seal materials available

on request.

TECHNICAL DETAILS

Maximum working pressure for both sizes of couplings

is 700 bar. Working temperature range with nitrile seals

is -20°C to +100°C
