Thread Sealants

Delta thread sealants replace the need for traditional hemp & paste, solvent based and PTFE sealing methods, while protecting against corrosion and resisting vibration. They are in single component liquid or gel form and suitable for most thread sizes, forming an instant low pressure seal.

D333 - Pipe Sealant with PTFE

A high viscosity anaerobic thread sealant of low/medium strength designed to lock and seal metal threaded pipes and fittings. The high lubricating properties provide easy assembly with no galling on all types of metal threaded pipes and fittings. An immediate low pressure seal is achieved once the fitting has been assembled.

Product Code: D333

Size: 50ml, 250ml

Colour: White

Strength: High / Paste

Viscosity: Medium

Service Temperature Range: -55°C to +200°C

Handling Time: 10-30 minutes in ambient conditions

Full Cure: 24 hours

D377 - Thread Sealant with PTFE - WRAS Approved (potable water use)

Widely used for the locking and sealing of metal threaded pipes and fittings, this anaerobic sealant cures when confined in the absence of air between close fitting metal surfaces and prevents loosening from shock and vibration. Ideal to seal against gases, water, LPG, hydrocarbons, oils and other chemicals, its excellent thixotropic property prevents migration of the sealant before or during curing.

Product Code: D377

Size: 50ml

Colour: Yellow

Strength: High - permanent grade

Viscosity: High / Paste

Service Temperature Range: -55°C to +150°C

Handling Time: 15-30 minutes in ambient conditions

Full Cure: 24 hours

D506 - Air Brake / Pipe Sealant with PTFE

A high performance anaerobic thread sealant designed for the locking and sealing of threaded pipes and fittings, while easing assembly due to the lubricating action of added PTFE. Packaged in a unique ‘concertina’ pack, giving easy application in even the most restricted areas, it is resistant to water, fuel, oils and most commonly encountered industrial fluids.

Product Code: D506

Size: 75ml

Colour: White

Strength: High / Paste

Viscosity: Very low

Service Temperature Range: -55°C to +150°C

Handling Time: 10-30 minutes in ambient conditions

Viscosity: Medium

Service Temperature Range: -55°C to +150°C

Handling Time: 10-30 minutes in ambient conditions

Full Cure: 24 hours


Retaining Compounds

Delta retaining compounds secure bearings, bushes and cylindrical parts into housings or shafts. Applied as a liquid, they form 100% contact between metal surfaces, allowing uniform load and stress distribution and eliminating the need for machining or other mechanical methods.

D22 - Bearing Grade Adhesive

A medium viscosity anaerobic adhesive for the retaining of bearings, cylindrical parts, bushes and oil seals that require later disassembly. Permits a sliding fit and eliminates distortion during assembly. The product offers high performance with controlled medium to high strength.

D55 - High Strenght Retaining Grade Adhesive

A very high strength anaerobic retaining compound for use when a permanent bond is required between closely fitting parts that are subject to stress, such as locking bushings and sleeves on shafts and housings. Can be used on gaps approaching 0.25mm, therefore useful for locking badly fitting parts.

Product Code: D55

Size: 50ml, 250ml
