MISCELLANEOUS COUPLINGS

HPA SERIES

HIGH PRESSURE, BALL SEAL, SCREWED COUPLINGS

" and 3/8 " NPT.

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

FEATURES

★ Compatible with all high pressure pump and cylindermanufacturers (Enerpac, SPX, Larzep and Hi-force) ★ Connection and disconnection can be performedeven with low residual hydraulic pressure in the line. ★ Screw thread retaining mechanism eliminatesBrinelling

APPLICATIONS

General industrial equipment

MATERIALS

Zinc plated carbon steel body material with nitrile sealsand PTFE backing ring. Other seal materials available on request.

PRESSURE DROP CHARACTERISTICS 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 ORDER CODES
