Washers, Sealing Rings, Insulating Rings, and More – in Laboratory and Chemical Technology

As a specialist in fastening technology, RCT offers a wide range of plastic discs, including washers, spacer & sealing rings made of PA (Polyamide). Also included in the assortment are sealing washers, insulating rings for screw protection (not for MIG torches as insulators), clamping & screw securing rings made of PA (Polyamide) and other plastics. Washers, sealing washers, and sealing rings made of PVC for Whitworth pipe threads are also part of RCT's program.

Materials in Use

The range of discs and rings is also offered in plastics such as POM (Delrin®), HDPE (High-Density Polyethylene), PVC-P (Soft PVC, THOMAVINYL), PVC-U (Hard PVC), PVDF (Kynar®, Solef®), and PTFE (THOMAFLON). The fastening elements also include axial clamping products made of POM (Delrin®) for securing shafts and axles, allowing for the absorption of axial forces in this context.

Conical insulating rings made of PA are used to secure countersunk screws. They find application in damping vibrations in apparatus construction and motor operation.

Double-sided rings as retainers and securing washers serve the secure protection of nutsscrews & bolts.

Screw securing rings are considered sealing rings and washers. They represent a proven screw securing and sealing solution, which has also proven effective for vibration and housing damping. Washers as screw securing, sealing washers, and sealing rings have their place in chemical technology, process engineering, and pharmaceutical technology, ensuring their best performance during the initial fastening.

A specialty are captive, sealing and securing washers made of PA, available in flat design as well as for M threads.

Discs and sealing rings with narrowly defined boreholes

A special group of plastic and sealing washers as well as  spacer,  sealing, insulating and retaining rings made of polyamide are products with tightly defined boreholes ranging from 12.2 to 13.2 mm, 14.0 to 15.1 mm, 16.0 to 18.5 mm, 2.2 to 20.5 mm, 20.0 to 21.0 mm, 22.0 to 25.0 mm, as well as 4.0 to 5.8 mm and 6.0 to 6.5 mm. This group of discs and rings serves as ideal sliding rings between rotating parts.

The high fatigue strength and excellent elastic recovery of PA washers, sealing washers, and sealing or spacer rings indicate high wear resistance and mechanical load capacity, providing grip at all times.

Resistance

Faceted PA (Polyamide) screw securing rings are resistant to diluted acids and alkalis, as well as to oils, gasoline, benzene, alcohols, esters, and ketones.

These products are resistant to aromatic and aliphatic hydrocarbons, as well as to mineral oils, lubricants, alcohols, esters, ketones, and amines. They are also resistant to weak alkalis and acids.

Standards
