Plasson Bucchi Easy/Quick Tank Adaptor Fitting for Installation on tanks with curved or uneven walls

The Plasson Bucchi Quick Install Tank Adaptor (QJ®) makes tank fittings fast, simple, and secure — no more struggling with awkward inside access or complex installations. Designed to be fitted entirely from the outside of the tank, the QJ® adaptor delivers a watertight seal in just seconds, even on curved or uneven tank walls.

Manufactured from tough polypropylene (PP) and equipped with a food-grade EPDM gasket, this adaptor is resistant to stress, vibration, temperature changes, and harsh weather conditions. Suitable for both plastic and steel tanks with wall thicknesses from 2mm to 12mm, the QJ® adaptor is ideal for use with water, fuels, and even aggressive liquids. Its hydraulic seal holds reliably up to 4 bar, ensuring long-lasting leak-free performance.

HOW TO INSTALL

1. Select correct size bucchi tank adaptor
2. Drill hole size according to chart overleaf
3. Insert so adaptor gasket is inside the tank 
4. Tighten until gasket is flat against the tank wall
5. Tighten with a wrench to ensure secure seal
6. Apply thread tape and install fittings

BEHIND THE TANK FITTING

Fitting tank connections is a fiddly, frustrating job usually requiring two people and exceptional hand-eye co-ordination but a clever Italian company is changing all that.

BUCCHI have spent years perfecting a tank connector design, called Quick Joints or QJ. Quick Joints can be installed in tank walls from the outside, without the need for welding, sealants or locknuts, and installation can be done by one person in a matter of seconds.

For over 40 years BUCCHI have developed fittings for farming, gardening, heating and air-conditioning. The quality of their seals is paramount so BUCCHI produce high-tech elastomer seals designed to handle dynamic movement and significant elastic deformations without changing original shape.

Dr. Anna Valentini, Head of Laboratory and Quality Control of BUCCHI, explains:

EPDM

An ethylene and propylene-based rubber with a third monomer (diene). It is particularly resistant to fluids such as water and vapour.
The gaskets in E.P.D.M. have high resistance to permanent deformation and a good breaking load (up to 180 kg cm2), with an operating temperature from -45° to + 130° C.

The EPDM compound resists corrosive chemical agents, oxidation, the ozone, heat, heat ageing; its resistance to high concentration acids is also good.
