CPS Smart Seal HK5SS refrigerant filling hoses, SAE 5/16, straight, 360° rotatable and leak-free connections

CPS Smart Seal HK5SS SAE 5/16 straight refrigerant charging hoses

The CPS Smart Seal HK5SS refrigerant charging hoses with straight SAE 5/16" fittings offer a safe, practical solution for refrigerant charging in refrigeration, air-conditioning and heat pump systems. Unlike conventional hoses, the fitting is mounted on a swivel joint: the hose can twist during connection without the already fitted connector coming loose. This prevents tension in the hose and ensures a permanently leak-proof connection.

Technical details

• Fully rotatable hose connection, 360° in both directions
• Leak-proof connections for maximum safety
• No tools required; simply tighten by hand (do not use pliers)
• Clear colour-coding of the hose lines for easy identification
• Reduced wear and tear, resulting in a longer service life for the hoses
• Pro-Set ‘Smart Seal’ technology for safe, efficient refrigerant charging
• Burst pressure: 4000 psi / 275 bar
• Operating pressure: 800 psi / 55 bar
• Length: 5 ft / 1.5 m
• Connection: SAE 5/16" straight

SmartSeal – Operating principle & benefits

• With standard hoses, the coupling is fixed to the hose. If one end is tightened and the other end is then connected, the hose can twist – in the worst-case scenario, the first coupling may come loose again slightly.
• SmartSeal hoses solve this everyday problem: the connector is mounted so that it can rotate freely. Even if one end is already firmly screwed on, the hose itself can still be twisted and repositioned without the connector coming loose.
• This makes installation considerably easier, prevents tension in the hose and ensures a permanently secure, leak-proof connection – a clear unique selling point compared to conventional hoses.
• Once the connection has been correctly tightened by hand, there is no risk of refrigerant leakage when the hose is subsequently rotated or moved; the sealed connection remains reliable.

Advantages and benefits

• Simple, quick installation thanks to freely rotatable fittings – no need to twist or untwist the hose
• More secure connections: reduced risk of already fitted fittings coming loose
• Tool-free handling: fittings can be fitted using just two fingers; no excessive tightening with pliers is required
• Less wear on the hose and fitting components, resulting in a longer service life
• Leak-proof design reduces refrigerant losses and improves workplace safety
